Does the engine loose revs, or the engine keep revving and just the chain stops? If the engine is still running at normal revs, and the chain slows down, then it’s a problem with the clutch. Worn out, gummed up, jammed springs etc. If the engine looses revs under load then it’s more likely a fuel or carb problem.
Do chainsaw clutches wear out?
Clutch Replacement When the clutch shoes wear out, it’s usually best to replace the entire clutch assembly because the inside of the drum is probably worn out, too. Start by unscrewing the spark plug and locking the piston with a locking tool or a piece of rope. Then you’ll have access to the clutch shoes.
