I heard rattling in my 66cc 2 stroke so I took the top end apart. I found damage on top of the piston, matching damage on the head, and the damaged part of the piston scraped down the cylinder wall. The motor still ran fine. maybe a loss of power? but still up to 30. so not too much. I did sand the head to get a good seal but there is still a slight part of that ring on the head. I ran it with no head gasket but didnt like how high the compression was because it was hard to start. Since that I've put maybe 150 miles on it WITH the a new metal head gasket. Could the piston have hit the head randomly like that? btw I have about 600 miles on the engine runnin 32:1 since 200 miles.
How do I fix this? really dont have money for a new engine or top end. It still ran earlier, so should I just slap it back together? sand down the damaged parts?
