Clogged carburetor:
A clogged carburetor can also cause a chainsaw to cut out. To fix this, you will need to clean the carburetor according to the manufacturer’s instructions.
Spark plug problems:
A faulty spark plug can prevent the engine from firing properly, causing it to cut out. To fix this, replace the spark plug with a new one.
