Why Does My Chainsaw Keep Stalling?

There are a few reasons why your chainsaw might be stalling.

The chain is too tight:
If the chain is too tight, it will be difficult for the engine to turn it over. This can cause the engine to stall. To check the chain tension, hold the chainsaw with the chain off the ground. The chain should have about 1/8 of play between the chain and the bar. If the chain is too tight, loosen the chain tensioner until there is the correct amount of play.

The chain is too loose:
If the chain is too loose, it will slap against the bar and cause the engine to stall. To check the chain tension, hold the chainsaw with the chain off the ground. The chain should have about 1/8 of play between the chain and the bar. If the chain is too loose, tighten the chain tensioner until there is the correct amount of play.

The carburetor is dirty:
A dirty carburetor can cause the engine to run lean, which can lead to stalling. To clean the carburetor, remove the air filter and carburetor cover. Use a carburetor cleaner to clean the carburetor jets and passages. Reinstall the air filter and carburetor cover.

The fuel filter is clogged:
A clogged fuel filter can restrict the flow of fuel to the engine, which can cause the engine to stall. To check the fuel filter, remove the fuel line from the carburetor. Look inside the fuel filter for any debris. If the fuel filter is clogged, replace it with a new one.

The spark plug is fouled:
A fouled spark plug can cause the engine to misfire, which can lead to stalling. To check the spark plug, remove it from the engine. Look at the spark plug tip. If the spark plug is black and sooty, it is fouled. Clean the spark plug with a spark plug cleaner or replace it with a new one.

The air filter is dirty:
A dirty air filter can restrict the flow of air to the engine, which can cause the engine to run lean, which can lead to stalling. To check the air filter, remove the air filter cover. Look at the air filter. If the air filter is dirty, replace it with a new one.

If you have tried all of these things and your chainsaw is still stalling, you may need to take it to a qualified chainsaw repair technician.
