hi, i'm new to the forum. my bike was running fine until i took it apart to replace a gasket i had seen hanging from the bottom as a result of a loose case screw. during reassembly, i broke about a cm. off of a piston ring and foolishly tried to run the engine with the damaged ring in place. it seized up, the broken edge catching on one of the openings in the cylinder wall.i was able to free the cylinder from the piston after much horsing and cussing, to discover a small, L-shaped gouge on the wall of the cylinder. i filed and sanded it out pretty well and replaced the broken ring and put it all back together. the bike won't run.
it turns over fine and i checked the spark by turning the wheel and it works fine, so, my question is how sensitive are these chinese kits when it comes to that piston? the compression seems okay, you can feel it in the spark-plug hole, and when plugged the bike seems about as hard to roll as it ever did. okay, a little bit easier. could a tiny air-leak between the piston and the cylinder be the cause of my bike not starting?
