Chainsaw Poulan 2150. Technical characteristics and operating instructions

Content

In the garden equipment market, the Poulan 2150 chainsaw has been a leader for a long time. Such popularity came to the instrument due to the high quality of materials, power, performance, moderate weight and small dimensions.

Low fuel and oil consumption makes the Poulan chainsaw very economical. The tool is falsely classified into a specific class, so I consider it universal. This is due to the fact that the Poulan 2150 chainsaw is perfect for both domestic use (harvesting firewood, cutting down dead wood) and professional use (felling trees, sawing wood, etc.)

Maintenance and repair of the Poulan 2150 chain saw

As practice shows, most requests from owners of Poulan equipment during the warranty period are related to improper maintenance and operation of the tools by the new owners. Therefore, we strongly recommend that you carefully study the operating and maintenance instructions and only then begin assembling the chain saw. However, this Poulan model has a number of disadvantages associated with uneven engine operation at idle or under load, in addition, the engine may have difficulty starting or starting and immediately stall. In this case, we first of all recommend paying attention to the quality of the fuel. It is possible that the fuel mixture has been stored for a long time or was made from low-quality gasoline. In any case, the fuel needs to be changed to fresh.

Another reason for rough engine operation can be a clogged air filter. We recommend cleaning the filter at the end of each working day; this will not only help increase the performance of the Poulan 2150 chainsaw, but also significantly reduce the consumption of fuel and lubricants.

However, most often, engine malfunctions are associated with incorrect carburetor settings. The manufacturer adjusts the carburetor at the factory, however, after some time they need to be adjusted. The unit can be repaired, cleaned and adjusted either at a service center or at home.

The carburetor is adjusted using three screws: L (responsible for idling), H (responsible for engine operation at high speeds) and screw T, responsible for the air supply. More detailed instructions for disassembling, assembling and adjusting the carburetor of the Poulan 2150 chainsaw are given here:

Basic equipment and production of the Poluan chainsaw

When purchasing a Poulan 2150 chainsaw, you receive it disassembled in the following configuration:

bar 40.5 cm long and saw chain;
casing for the bar for transporting and storing the saw;
engine oil;
oil for lubricating the chain during operation;
a set of keys for assembly and maintenance;
technical documentation, instructions, warranty card.

Poulan is famous for assembling its products in-house at its own factory in Nashville, USA. However, sometimes you can find a Chinese or European-assembled chainsaw on the market. It is not recommended to purchase such a chain saw, as there is a risk of purchasing a low-quality fake.

When purchasing a Poulan, special attention should be paid to the documents that come with the chainsaw.

Features of use and safety precautions

In order to avoid injury to the operator, before using the Poulan 2150 chainsaw, it is important to study the operating manual in detail, where special attention is paid to safety precautions. Only a rested person who is protected by special clothing can operate a Poulan chainsaw. It consists of safety glasses, earmuffs and gloves, fitted clothing that does not restrict movement and closed, tight boots.

The Poulan 2150 chainsaw runs on a gasoline engine, which means it produces exhaust gases that are harmful and poisonous to humans. It is for this reason that the chainsaw should not be used in closed and poorly ventilated areas, near sources of fire and sparks.

Do not forget that fuel is a flammable liquid and, in order to eliminate the possibility of fire, it is necessary to carefully check the Poulan saw for fuel or oil leaks.

An internal combustion engine works by burning a pre-prepared mixture of air, oil and gasoline. Adjusting the carburetor chainsaw is necessary to prepare the mixture in the required proportion. It depends on the carburetor whether the engine will perform at its advertised power or stall.

Maintenance and instruction manual

As mentioned earlier, it is important to study the instructions for use, which describe important points of safety, use, maintenance and repair. Since the Poulan 2150 chainsaw is manufactured in America, it is difficult to find a manual in Russian.

The Poulan 2150 chainsaw has a fuel tank capacity of 0.35 liters. at normal and average engine load, the chain saw consumes fuel in the amount of 370 g/kW h. The oil tank has a volume of 0.2 liters. The manufacturer himself recommends using high-quality motor oil for refueling.

Avoid using waste as it may cause serious damage to the pumping system. A mixture of AI-92 gasoline and oil for two-stroke engines in a ratio of 25:1 is suitable as fuel for the saw.

Carburetor adjustment

No matter how carefully the maintenance of the Poulan is carried out, some breakdowns are possible. The instructions will give you some troubleshooting information. If the problem is serious, then it is best to seek help from a service center, where an experienced and qualified specialist will diagnose and carry out the necessary repairs.

Adjusting the carburetor in the Poulan 2150 chainsaw may be necessary if the operator notices difficulties with idling.

Chainsaw Poulan 2150

Poulan 2150 is one of the best-selling models in its class. The Poulan chainsaw has compact dimensions, light weight and a stylish modern design. The tool belongs to the household class and can be used for harvesting and sawing firewood, performing landscaping work and caring for the garden and hedges. The average power engine (1.8 kW) and light weight (4.7 kg) make it possible to use the Poulan 2150 chainsaw in the construction and repair of residential buildings, sheds, bathhouses, gazebos, garages, and other utility rooms.

Technical characteristics and parameters

The saw's autonomy is ensured by a standard two-stroke carburetor engine with a displacement of 36 cm3, developing a power of 1.8 hp at 13,000 rpm.

The power unit runs on a mixture of motor gasoline and oil for two-stroke internal combustion engines in a combination of 25:1. Fuel is taken from a built-in fuel tank with a volume of 350 ml.
The combination of a wear-resistant coating on the inner diameter of the cylinder and a low coefficient of friction of the piston group material allows the use of the engine's traction capabilities with minimal power losses.
The electronic ignition system ensures complete spark generation and guarantees reliable engine starting at low temperatures, stable operation at idle and operating modes.

Brand Poulan

Poulan was created in the last years of World War II in the United States, when demand for compact household tools increased throughout the world. The founder of the company, Claude Paulan, assumed that the renovation of old and construction of new houses would soon begin and people would need woodworking tools. This is how Poulan chainsaws appeared on the world market. Thanks to reasonable pricing policy and high quality products, the company's products have gained popularity not only in the United States, but also far beyond America.

Until recently, all Poulan chainsaws were assembled at the American plant in Nashville. More recently, information has emerged that the company has transferred part of its production capacity to China, where the Poulan 2150 model is also produced. All Chinese-assembled products meet the corporation’s internal quality standards and have the appropriate American and European certificates. On the post-Soviet market, a Poulan 2150 chainsaw can be bought for 100 – 120 dollars.

Specifications

Each buyer of a new unit receives a package of necessary documents in paper format. An electronic description of the Poulan 2150 chainsaw, its technical characteristics and instruction manual are available here:

Carburetor maintenance and adjustment

The main complaints from users of this Poulan model relate to the fact that the engine starts and may stall, runs unevenly or with dips.

First of all, we recommend paying attention to the air filter. It must be thoroughly cleaned, and in some cases washed in gasoline. Most often, after this procedure, engine performance improves, but failures and dips in speed can still be observed.

In this case, we cannot do without adjusting the carburetor. The adjustment operation is carried out with three screws marked L (adjusts the quality of the mixture at idle gasoline), H (responsible for the quality of the mixture at high speeds) and screw T, responsible for idling the engine.

At the first stage of setting up the carburetor, tighten the screws L and H until they stop, then unscrew them back one and a half turns;
We try to start the engine. If this does not work immediately, we repeat the attempts, first turning the screw T by ¼ turns until we start the engine;
Let the engine warm up for 8-10 minutes, then use screw H to increase the engine speed to maximum and unscrew the screw from this point a quarter turn;
Use the idle screw to reset the engine speed to normal;
We check the engine response by running it in different modes.

Adjusting the Poulan chainsaw carburetor

Setting up a failed carburetor on a Poulan saw is practically no different from a similar procedure with models from other manufacturers. To adjust the unit yourself, you need to make sure that the fuel system is working properly, as well as the cleanliness of the fuel filter.

All unnecessary parts will need to be removed. To do this, you need to disconnect the upper protective plastic shield, the air filter, the fuel line and the drive rod. You also need to remove the end of the standard cable.

There are 3 small bolts on the side of the Poulan chainsaw, by turning which the owner of the model can adjust the operation of the carburetor. Under each of the screws there are markings in the form of the letters L, H and T. The first bolt is needed to adjust the motor when operating at low speeds, the second – regulates the operation of the engine at high speeds. The third screw is needed to adjust the idle speed. The factory carburetor setting algorithm should look like this:

First you will need to return all the bolts to the factory settings;
After this, you need to start the chainsaw and start turning the bolt L until the engine begins to rotate at the highest speed. Once the motor shaft reaches maximum speed, bolt L will need to be turned 1/4 turn in the opposite direction;
Next, you will need to connect a tachometer to the Poulan saw and start turning bolt H until the motor reaches maximum speed. After this, you need to compare the tachometer readings with the instructions in the engine operating instructions. If the indicators match, then you need to move on to the next stage;
If, when the engine is running at maximum speed, the chain on the standard tire begins to rotate, then you need to start turning screw T in different directions. This must be done until the chain stops.

Owner reviews

Nikolay Astakhov, 44 years old, Primorsky Territory:

I bought the Poulan 2150 saw four years ago. I use it regularly, mainly for harvesting and sawing firewood. My assembly is still American, according to the documents. No special problems were identified during this time. The motor runs fine, the tire and chain are of acceptable quality. During all this time I adjusted the carburetor a couple of times and bought a couple of chains.

Victor Rybak, 43 years old, Arkhangelsk region:

Poulan bought the saw as American, but it turned out that it was made in China. However, in terms of the quality of the parts and assembly of the unit, everything is quite acceptable. The engine is practically indestructible. I seriously loaded it - it cuts perfectly. Of course, during this time it was not without problems. The main one is the carburetor. It has to be adjusted regularly. The Poulan 2150 chainsaw is very susceptible to air filter contamination: it gets a little dirty and the speed already fluctuates.

Advantages of the Poulan model: price, high-quality engine, no vibration;

Disadvantages: carburetor settings are often lost, Poulan reacts strongly to air filter contamination.

Main advantages and disadvantages

Pros:

Reliable high-speed engine;
The piston group parts are made of high-strength materials and have a chrome plated finish;
Two-stage air purification system;
Ergonomic, well-balanced body;
Effective anti-vibration system on damper springs;
High-quality Poulan saw set.

Minuses:

Some instruments only come with an English manual;
Carburetor settings are often lost;
The engine needs a high-quality and fresh fuel mixture;
There are many counterfeits of instruments from this brand on the market.

What carburetors are used on Chinese chainsaws

The most optimal carburetor designs for chainsaws were developed by the world's leading manufacturers - German Stihl, Japanese Walbro and others. These top developments are hard to beat. Therefore, most Chinese manufacturers copy the best models.

Today there is a large offer of Chinese carburetors for chainsaws on sale.

Some are nameless, from an unknown manufacturer and do not even have markings. They are simply offered for a specific chainsaw model. For example, a carburetor for a Stihl MS 361 chainsaw.

Others have brand names of well-known brands.

Still others have their own catchy names - in Russian transcription King Kong, Technopark, Rezet and others.

Features of the Chinese chainsaw carburetor

Their design and parameters differ depending on the power and model of chainsaw they are intended for. All of them are almost identical to the original carburetors in design, but not always in quality. Today, all Chinese products cannot be considered 100% rubbish. In turn, according to their quality, they can be divided into three groups:

Poor quality. Unsuitable alloys are used which oxidize, crumble and break. There is no accuracy of fit, the calibrated holes do not correspond to the required values, which leads to excessive consumption or lack of fuel in the combustion chamber. Critical parts quickly fail. Plastic parts quickly become rough or, conversely, become softened by gasoline and stop working. The axles and wire rods are bent, the threads of the fasteners are torn off. Such products are the cheapest. They are made in semi-handicraft industries using adapted equipment. As a rule, they do not have a name or marking.
Carburetors are of average quality. These are factory assembled products. They do not skimp on alloys; they have established continuous production with quality control. These are fully functional carburetors that can have a service life even longer than that of the entire chainsaw.
High quality carburetors. First of all, these are products from global manufacturers whose facilities are located in China. Geographically, they can be considered Chinese, but they are made using the technologies of the company that owns the brand and values its reputation. For example, Japanese Walbro carburetors are produced in China.

In addition, among Chinese manufacturers there are those who rely on high quality. They invest heavily in powerful production facilities, register their own brand and work on its reputation.

Poulan Chainsaw Carburetor Adjustment

Why and how to adjust a chainsaw carburetor

A gasoline engine works by burning a previously prepared mixture of air, oil and gasoline. Adjusting the chainsaw carburetor is necessary to prepare the mixture in the required proportion. The operation of the carburetor determines whether the engine will work with the declared power or stall.

The principle of operation of the carburetor

Regardless of the manufacturer, the principle and operating procedure of the carburetor of internal combustion engines is similar. For mixing air and fuel, the carburetor is a device that includes:

air tube with constriction;
fuel supply system;
adjustable air damper.

Air under atmospheric pressure, having passed the air cleaner, is supplied to the narrowing zone, where its flow is regulated by a flat damper blocking the cross-section. After the narrowing, a vacuum appears in the pipe. As a result, the vacuum sucks fuel from the fuel supply tube, the outlet of which is regulated by a fuel needle connected to the float chamber by a nozzle. The design of a chainsaw carburetor is, in principle, no different from other fuel mixers in internal combustion engines.

The principle of mixing is to regulate the air damper and float level, depending on the degree of vacuum. We open the air - more fuel comes in, the engine increases speed. The correct ratio of combustible consistency depends on the precise adjustment of the chainsaw carburetor. If there is a lot of air in the fuel, the power drops and the mixture is called lean. If there is not enough air, there is a high fuel consumption, incomplete combustion, carbon deposits on the cylinder and the release of unburned fuel. This states that the mixture is supersaturated.

According to the instructions, the Ural chainsaw requires running-in using an enriched fuel mixture. Therefore, the carburetor comes from the factory with the setting for the break-in period. When switching to operating mode, the node is configured again.

Signs that a chainsaw carburetor is working well:

the engine runs smoothly, resembling a four-stroke sound;
quick set of revolutions;
At idle the chain does not turn.

When is carburetor adjustment required?

The new chainsaw is adjusted to the recommended mixture. It will only require precise adjustment using three screws; there is no need to disassemble the carburetor. Purpose of adjusting screws:

.

“L” regulates fuel supply at low speeds;
“H” is needed to regulate the maximum fuel supply;
"T" idle air control.

Since the saw carburetor is adjusted by ear while the engine is running, safety precautions must be observed. The saw must be positioned stable with the cutters pointed in a direction that is safe for those present.

Before starting manipulations, it is necessary to mark the initial position of the screws with paint or a felt-tip pen. The exact settings for the chainsaw carburetor for each model are in the operating instructions.

However, more often it is necessary to adjust the carburetor after eliminating a malfunction of the tool. The reasons may be:

violation of the protective cap and unbalancing of the screws;
wear of the engine piston, requiring a different mixture composition for operation;
unsatisfactory performance of the carburetor itself.

How to adjust the carburetor on a specific model of chainsaw? Perform the operations sequentially, following the instructions. Here is the algorithm, the general sequence of actions.

There are two stages of setup:

basic, with the engine off;
thin - on a warm engine, idling.

The basic setting is carried out only for the fuel screws at low and high speeds. Smoothly and slowly, close the dampers completely until they stop. Also smoothly open both screws counterclockwise 1.5 turns. After this, start the engine and warm it up for 10 minutes.

How to adjust the carburetor on a chainsaw with the engine running:

adjust the idle speed with screw “T” by rotating counterclockwise until the engine runs stable at idle speed;
check the speed of the speed increase; when spinning slowly, turn screw L an additional 1/8 turn;
Set the highest rotation speed using screw H on the tachometer;
Check the carburetor operation at idle once and for all.

How to find a carburetor malfunction

However, adjustment may be preceded by repair of the carburetor itself when it cannot fulfill its function as a fuel mixer.

Adjusting the carburetor of a Chinese chainsaw with your own hands

Adjustment is not provided on all carburetors of Chinese chainsaws. Today there are many models of household chainsaws, including European brands, whose carburetors simply do not have adjusting screws. Or there is only one idle speed adjustment screw.

Such carburetors require adjustment only when the chainsaw at idle makes too few emissions (revolutions) and sometimes stalls. Below in the text we will discuss the algorithm for adjusting the idle speed of the carburetor on a Chinese chainsaw.

Required Tools

Adjustment requires a screwdriver that fits the slots of the adjustment screws. On different carburetors they are flat, cross-shaped, with an internal or external hexagon, an asterisk, etc.

An electronic tachometer will help with adjustment. If it is not there, adjustment is carried out by ear and by assessing the actual operation of the engine.

Carburetor adjustment algorithm

Before making adjustments, make sure it is necessary. All Chinese carburetors on each chainsaw undergo factory settings, which rarely go wrong. A new carburetor, or in rare cases an old one, may require adjustment.

The cause of deterioration in engine performance with symptoms similar to poor supply of the fuel mixture is, in most cases, the following:

clogged air filter,
exhaust windows and muffler clogged with carbon deposits,
bad fuel.

If this is not the problem, then try adjusting the carburetor.

The engine must be warm. A cold engine and one warmed up to operating temperatures operate differently. Therefore, adjustment in cold conditions will be incorrect.

Provide access to the adjusting screws. On some chainsaws, it is enough to remove the cover and air cleaner. On others you have to remove part of the body. On the third, the housing has holes for a screwdriver.
The screws are marked on the carburetor or near the holes - T (or LA) L and H. The T (or LA) screw is designed to adjust the idle speed. Always located away from screws L and H, which are next to each other.
If the chainsaw stalls when gas is supplied, the engine does not have enough fuel to develop speed. The amount of fuel is adjusted using screw H (main screw). Unscrew it 1/4 turn and give gas. If the engine begins to work better, unscrew it another 1/4 turn. (If worse, then tighten it 1/4 turn in the opposite direction).
If the engine starts to idle, it means there is a lot of fuel, screw H is screwed back.
The peak speed is controlled by ear or using a tachometer. The maximum speed for each chainsaw is indicated in the instructions. (10,000 – 12,500 rpm). In practice, 10,000 – 11,000 rpm in the “full throttle” position are normal values.
By increasing the amount of fuel supplied with screw H, the quality of the fuel mixture is adjusted with screw L. It increases and decreases the amount of air in the mixture. If there is not enough air, the fuel will not burn out; as a result, the engine smokes, does not develop power and consumes excess fuel. Screw L also affects engine operation at low and medium speeds.
After adjusting screw H, screw L is unscrewed 1/4 turn. If there is smoke in the exhaust and the engine moves from low to medium and high speeds with dips, screw L is unscrewed some more.
Adjustment of screw L is stopped when the engine runs smoothly, moves smoothly from low to high speeds and does not smoke.

Do-it-yourself chainsaw carburetor adjustment

For an independent carburetor option, you need to familiarize yourself with its structure and understand the procedure for the work that is carried out to adjust the parts responsible for the proper functioning of the components of the device and parts close to it.

It is necessary to carefully handle items for the system option, and also to determine whether the set characteristics correspond to very acceptable values.

About the carburetor design

The carburetor serves to mix the flammable mixture with air while maintaining predetermined proportions. If clear doses are not followed, the proper operation of the engine is at risk. When a huge amount of air enters during mixing of the components, but there is not enough fuel, then such a mixture is considered “lean”.

Oversaturation should not be allowed, because with a larger amount of fuel compared to air, malfunctions or engine wear are also likely. Carburetor adjustment is needed not only before initial use, but also when any differences in its operation are detected. Before working with a chainsaw, do not forget to run it in.

Carburetor components

The carburetor design contains a standard set of parts, but may vary slightly depending on the manufacturer. Components:

The basis . This is a special tube that is visually similar to an aerodynamic design. Air passes through it. In the transverse direction, a damper is located in the middle of the pipe. Its position can be changed. Adjusting the Poulan 2150 chainsaw - forum. The more it is extended into the passage, the less air enters the engine.
Diffuser . This is the constricted part of the tube. With its help, the air supply speed increases precisely in the segment from which the fuel comes out.
Channels for fuel supply. The fuel mixture is contained in the float chamber, then passes into the nozzle, from which it flows into the atomizer.
Float chamber . It is a separate structural element, reminiscent of the shape of a tank.

What you need to have for setup

Each carburetor owner must have the necessary tools to adjust this system. There are three adjustment screws that are located on the body of the device. They have their own markings:

L - screw for correcting low speeds.
H - screw for adjusting high speed.
T - regulates idle speed, in most cases used for experiments.

Chainsaw air filter

Before adjusting the carburetor, you need to prepare the device:

The engine warms up, that is, it starts about 10 minutes before repairs, and turns off when starting work (see how to start a chainsaw).
The air filter is checked and washed.
The chain is stopped by turning screw T until it stops (see chain oil).

To carry out a safe repair, you need to prepare a flat surface where you can carefully place the device and turn the chain in the opposite direction. Need a tachometer. It determines whether there is a malfunction in the carburetor. When turning the screws, the sound should be perfect and absolutely smooth. If you notice squealing notes, the mixture is oversaturated.

Setup instructions

Carburetor adjustment is divided into two main stages. The first one is called basic. It is performed with the engine running. The second is performed when the engine is warm.

To carry out the carburetor setup procedure successfully, you need to read the operating instructions for a specific model in advance to identify additional features of setting up the device.

First stage

The adjusting screws for the highest and lowest speeds should be moved clockwise until the highest resistance is met. When the screws reach the stop, you need to move them in the opposite direction and leave them 1.5 turns.

Main stage

The engine is turned on at medium speed and warms up for about 10 minutes. The screw responsible for adjusting the idle speed should move clockwise. Another adjustment of the saw https: resuscitation of the Poulan 2150 chainsaw 2005 Poulan 2150. It is released only when the engine reaches stable operation mode. It is necessary to ensure that the chain does not move during this process.

In idling mode, the engine may stall (the reason is here). In this case, you must immediately turn the adjusting screw clockwise until it stops. Sometimes the chain starts to move. In this case, turn the adjusting screw in the opposite direction.

Checking acceleration operation

Need to do a little research. Acceleration of the device is initiated. It is necessary to evaluate the proper operation of the engine during maximum speed. Poulan chainsaws. Adjusting carburetors. Poulan 2150. Chainsaw Poulan 2150. When the engine is functioning correctly, it means that when you press the accelerator, the speed quickly increases to 15,000 rpm.

If this does not happen or the increase in speed is too slow, you must use the screw marked L. It turns counterclockwise. Moderate movements must be observed, since the turn cannot be more than 1/8 of a full circle.

Maximum number of revolutions

To limit this indicator, you need to use a screw marked H. To increase the number of revolutions, turn it clockwise, and to reduce them in the opposite direction. The maximum frequency should not exceed 15000 rpm.

If you make this figure larger, the device’s engine will wear out, which will lead to problems in the ignition system. When rotating this screw, you need to take into account the ignition processes of the device. Advantages, disadvantages, price, technical characteristics, analogues, adjustment and reviews from owners of the Poulan 2150 chainsaw. If the slightest glitches appear, then the maximum speed value must be reduced.

Final check at idle

Before this procedure, it is necessary to carry out a full adjustment of the carburetor components when operating at maximum speed. Next, you should check the functioning of the device in idle cold mode. When the correct adjustment parameters are achieved, you will notice that the carburetor design closely matches the following criteria:

When the idle cold mode is activated, the chain does not move.

Adjustment procedure:

Activities begin in idle mode . Using the adjusting screws, you need to achieve a systematic increase in engine speed, so you should first let it run at low speeds. A deviation from the norm is the movement of the chain along the bus. In this case, you need to adjust the outer screws to the optimal position so that the chain remains motionless.
The transition to medium speed speed is carried out . Sometimes the engine starts to smoke. This defect can be eliminated by tightening the screw to supply a leaner fuel mixture.

In this case, the smoke will disappear, but the engine speed will increase. You need to adjust the settings until you reach a level where, when you press the throttle, the engine smoothly picks up speed, and no sudden jerks or interruptions are heard.

Chinese chainsaw carburetor repair

Carburetors cost 500-1000 rubles. It doesn't always make sense to repair. A repair kit with a set of gaskets and a diaphragm costs not much less than the cheapest carburetor, 300-350 rubles. A frequent breakdown of Chinese carburetors is the failure of the injector valve, and such a part is not sold in repair kits. Therefore, it is easier to buy a new carburetor.

But there are breakdowns that can be relatively easily fixed on your own:

Loss of seal between parts of the carburetor body or between the carburetor and the engine. Sometimes it is enough to tighten the fastening screws. In other cases, you can remove the carburetor, replace the gaskets, or use a suitable sealant along with them.

Obvious mechanical problems - deformation of the wire rod from the throttle, sticking of the axes on which the throttle and air dampers rotate - are also easy to fix. The thrusts are straightened. The axle landing sites are lubricated with a drop of oil and free rotation is developed by hand.

Carburetor cleaning

The carburetor air filter needs to be cleaned periodically. They come in different types. From some it is enough to knock out dust and dirt by knocking on wood. Others are washed with soapy water. Still others require disassembly. The fourth ones are almost impossible to clean; they need to be replaced with a new one.

The features of the air filter for each chainsaw and maintenance rules are described in the instruction manual for each specific model.

If there is a filter in the gas tank, nothing can become clogged in the carburetor. If there is still a suspicion that the tiny holes in the jet are clogged, the carburetor is disassembled. The parts are laid out on a clean cloth, remembering which one comes from where. The holes are purged with a pump or compressor. The body and parts are washed in kerosene or gasoline.

There is no need to bring the condition of the filters to such a deplorable state. This greatly affects the performance and life of the chainsaw engine.

Gasoline does not flow into the carburetor: what to do

The fuel line from the gas tank is short and uncomplicated. Three problems may arise in this area:

The gasoline supply hose is pinched. The break is found, the hose is straightened or replaced if the round shape is not restored.
The filter at the bottom of the gas tank, which is installed on some models of chainsaws, is clogged. It is removed with a thin wire hook, inspected and cleaned. The gas tank is flushed with gasoline.
The breather has failed. When fuel is sucked in, a vacuum is created in the gas tank, and fuel flows poorly or does not flow at all. This part cannot be repaired. Most often, the breather is located in a hard-to-reach place, at the outlet of the fuel line from the gas tank. It is replaced with a new one.

Sometimes, instead of repairing the breather, a hole with a diameter of 0.2-0.5 mm is made in the gas tank cap. The downside is that gasoline may leak through the hole during operation, and after operation the chainsaw can only be placed on its side, with the gas tank cap facing up.

How are things going with repair kits?

The repair kit can be purchased at the same retail outlets where carburetors are sold. They are sold in two configurations:

rubber-plastic parts (gaskets, diaphragm)
the same thing, plus a cross with a needle valve.

It is difficult to find other spare parts separately.

Pros and cons of Chinese carburetors

Chinese carburetors can be of low, medium and high quality. Low quality products have the advantage of extremely low prices. The best option in terms of price-quality ratio is, as a rule, in the middle price segment.

An original European-assembled Stihl carburetor or a purely Japanese Walbro carburetor are excellent in quality. But their cost is sometimes equal to the price of an entire Chinese chainsaw. Therefore, it is better to confidently navigate the wide variety of Chinese carburetors with which our market is flooded, and make an appropriate choice.
