So did you figure out what caused it?

It would be a shame to do the mods that you want to do, only to find that it blows up soon after the re build.

There is a great need to work out what happened to cause it it die, things usually dont just happen.

Sounds like one hell of a vacuum leak from the carb leaking if the cap was stripped.

yeah I have no idea why I almost lost the rod bearings or why the piston was fries the only thing I could think is that the previous owner, at one time, put sraight fuel in it and almost over heated the thing. the rings were stuck on one side of the piston. indicating that at one time it had to be pretty hot. I will try to get the pics up her to show yall what im seing.

Symptoms of an air leak, or the incorrect jetting.
