Once I read your response Jeff I realized that a bead makes perfect sense, thank you.
Greg, I file fit the rings and opened them up to .035+. All the pistons I have hurt have been destroyed by detonation. One set broke Every skirt off every piston. I'm still trying to figure how it can rattle a piston that hard in a properly clearance bore
Sometime this week I'm going to try a 750 Eddy on it.
