Stihl ms251c: Suddenly dies while cutting

If your Stihl ms251c chainsaw suddenly dies while cutting, there are a few possible reasons why. The most common reason is that the chainsaw has run out of gas. If this is the case, simply refill the gas tank and try again.

Another possibility is that the air filter is dirty and needs to be replaced. A dirty air filter can restrict air flow to the engine, causing it to stall. To check the air filter, remove it from the chainsaw and hold it up to a light. If you can’t see through it, it’s time to replace it.

It’s also possible that the spark plug is dirty or faulty. A dirty spark plug can prevent the engine from starting, or cause it to stall while running. To clean the spark plug, remove it from the chainsaw and scrub it with a wire brush. If it’s still dirty, replace it with a new one.

If your chainsaw is still stalling, it’s likely that there is a problem with the carburetor. The carburetor mixes air and gas before it’s drawn into the engine, and if it’s not working properly, the engine can stall. To clean the carburetor, remove it from the chainsaw and soak it in a bucket of carburetor cleaner. Once it’s clean, reattach it and try starting the chainsaw again.
