Like Rangerfredbob and Buck said, it's a good engine and if the cylinder isn't scored above the exhaust port it would probably be fine with a new ring. I really like the Echo engines and have a number of them.

I recommend Frank Bowman rings. Just use one of his rings in the top groove, and one of the original rings in the second. Here's his contact info. [email protected], 505-327-0696
