How To Fix A HUSQVARNA 240 Chainsaw That Won’t Stay Running

by HIPA Jeremy 27 Sep 2022 0 Comments

Chainsaw won’t stay running has been a common problem. Now we will show you how to fix it on a Husqvarna chainsaw. It may not be the exact repair you need to make to yours.



Check the condition of the fuel in the fuel tank. You need to check if the fuel is old, stale or it has water in it. If the color of the fuel is a bit light that means there is not enough two-cycle oil mixed with the gasoline.

This is not going to immediately destroy the engine but it is one of the reasons why the engine is not going to last a long time. Now the oil is very important for a two-cycle engine as it helps to lubricate the engine to make it run fine.

Fuel Filter

Another reason why your chainsaw might not stay running is a missing or detached fuel filter. Without a fuel filter, the internal screen in the carburetor will clog up with debris and cause you to have running or even starting problems.

How To

Step 1: Remove the top cover and check the condition of the spark plug. If the spark plug tip is brown like it is supposed to be, so the engine seems to be getting enough fuel; if your spark plug tip is dark, then your engine is getting too much fuel and your carburetor will need an adjustment.

Step 2: Check the condition of your air filter. Make sure the air filter is not clogged with dirt or wood chips as a clogged air filter will also cause your engine to run poorly.

Step 3: Carburetor adjustment. If you have to make anything more than a slight adjustment then you need to remove the carb and inspect it for any problems.

Firstly, you need a flat screwdriver to adjust the idle speed by using the hole marked with the letter T, turn the screw clockwise to increase the idle speed and turn it counterclockwise to decrease the idle speed.

The L screw is for adjusting fuel delivery at high engine speeds when the trigger is fully squeezed. Turning the screw clockwise will decrease the fuel delivery while turning it counterclockwise is to increase the fuel delivery.

Step 4: Now you need to put your chainsaw on the ground and try to start it. If it still dies almost immediately after taking out a choke, what usually happens is that the metering diaphragm inside the carb is beginning to harden up which could cause this problem. To adjust for this, you need to increase the fuel delivery at idle speed.
