With small 2 stroke engines, it is easy to see the condition of the piston and cyl by removing the muffler and looking into the exhaust port. Before that though, check to see that you have AT LEAST 85-90 psi compression. If you don't NWR (not worth repair) well I take that back. ( I still had Roybi on my mind) Husqvarna cyl & piston kits are re$onable.
