Adjusting the Carburetor of the Oleo Mak 941c Chainsaw

When adjustment may be needed

Not a bad chainsaw

Stihl 100 eighty (or no matter what other) should serve you for a long time. But everything happens

The most common prerequisites:

• Loose mounting screws
• The engine was worn out (in this case, regulating a chainsaw like Goodluck or Sturm will only help for a while; in general, it’s better to immediately take it for repairs)
• The carburetor is clogged (in this case it will also have to be cleaned).

. How to set up a carburetor

The chainsaw option method is quite simple and consists of the following steps:

• Motor adjustment for smooth operation at low rpm.
• Adjusting the carburetor to properly deliver the fuel mixture at the highest speed.
• Narrow carburetor adjustment for idle speed.
• Checking with a chainsaw in all modes.

Now let's figure out how to more carefully adjust the carburetor of a chainsaw. Virtually all carburetor models have three adjustment screws. Screw (T) is responsible for the narrow setting in standby mode. Adjust screw (H) for highest speed. Screw (L) keeps consistency formation at low rpm under control. By tightening screws (L) and (H), the supply of fuel and mixture becomes weaker, and the speed increases accordingly.

The ignition is modern - electronic. To make starting easier, the saw is equipped with a primer for pumping fuel.

Adjustment of the Urals

It differs little in that it should not be carried out at sharp maximum speeds, but make sure that the chain picks them up quickly, but smoothly, without moving along the tire.

In any case, you should take the adjustment especially seriously, because if it is not done correctly, the saw will not stay with you for a long time. Take care of your own tools and if you are not convinced of your own abilities, contact a specialist.

Step by step adjustment

Let's analyze an example of carburetor adjustment using the Oleo Mak 937 chainsaw as an example. The principle of regulating other pollen is actually similar, therefore this method is applicable for subsequent models: 941c, 936. With other, less popular models (for example, Oleo Mak three hundred sixty-two or Oleo Mak 35 ) similarities are not checked, but most likely there are no severe differences.

Before setting up a carburetor for an Oleo-Mac chainsaw , you need to fulfill a number of criteria:

• clean air and fuel filters;
• check the condition of the jets, make sure they are in good working order and clean;
• assess the integrity of the membranes: no damage or cracks;
• check if there is enough fuel in the chamber.

No disassembly is required for standard carburetor adjustments. There are screws on the outside that allow you to make all the necessary adjustments:

• L low speed;
• H highest speed;
• S normal.

Although the manufacturer advises only adjusting screw S, in practice this is not enough. Before adjusting, all three screws should be tightened until they stop, and then unscrewed 1.5-2 turns.

The adjustment is made in stages as follows:

• The engine starts and warms up for 3-5 minutes at medium speed.
• tachometer is connected.
• Low speed operation is adjusted using screw L. You need to reach 1-1.5 thousand rpm. the engine without reversing the chain, and when you press the accelerator the speed does not drop. If a malfunction is found, the screw should be unscrewed until this effect is completely eliminated.
• The highest speed of the motor is regulated by screw H. When the accelerator is pressed to maximum, they keep the acceleration under control, it is important that they do not exceed the very permissible value. It is recommended to set it 5-10% below the highest speed, so as not to provoke increased wear on the gasoline engine.
• The carburetor is finely tuned using screw S. When the chain is idling, the screw should be turned counterclockwise until it stops. If the gasoline engine freezes, the screw is unscrewed clockwise until smooth operation is obtained.
• After the option procedures, the chainsaw is tested under real operating conditions. Make the options again if necessary.
