Not a reed valve engine. Unfortunately these saws have a non-plated cylinder and a chrome plated piston which means any gouges in the cylinder cannot be recovered. A new P&C combo is available on ebay for a low price and is a good upgrade as it is a chrome plated cylinder and non-plated piston. Will also boost the engine up to 42cc. Do this upgrade, open up the muffler and you will have a good light weight saw with decent power and long lifetime. Learn to tune the saw by the sound of the exhaust properly and you will avoid another lean-run self destruction. Good luck, could be an interesting learning project.
