Why Does My Chainsaw Keep Turning Off?

Your chainsaw keeps turning off because of a few possible reasons.

The carburetor is dirty. This is the most common cause of a chainsaw shutting off. The carburetor mixes fuel and air to create a combustible mixture that powers the chainsaw. If the carburetor is dirty, it can’t properly mix the fuel and air, which will cause the chainsaw to stall.
The spark plug is fouled. The spark plug ignites the fuel/air mixture in the chainsaw’s cylinder. If the spark plug is fouled, it can’t create a spark, which will cause the chainsaw to stall.
The chainsaw is out of fuel. This is a simple problem to fix, but it’s also one of the most common causes of a chainsaw shutting off.
The chainsaw is overheating. If the chainsaw gets too hot, it will shut off to prevent damage to the engine.
