I just tore my motor down and found a snap ring and a washer on my fly wheel stuck to the magnet. I took the clutch side cover off and looked at the idler gears and the snap rings are still on them. I have been into many of these bottom ends and i cant think of where it could have come from. the washers the size of a nickle as is the snap ring. The snap ring is bent u so it happened while it was running. Any ideas?
