Plenty of times. Seen and done it. If you run it too lean or just run it forever or any mild catastrophe happens you lose compression. Usually the rings are toast. Hopefully you re lucky enough to be buying some rings and a piston plus the gaskets. You won't know until you pull it apart and inspect cylinder and ports. Quick check piston by pulling exhaust off and rotate around slowly with kicker. Inspect rings and piston skirt. Should look new, not like you were dragging it behind your truck down the interstate!!! If they look good, it could still be a hole in piston or somethin, you kinda are hoping for mild damage to rings. Should be tough to kick thru without standing on it. Jug would be very hot, anyways, but no kick compression has to be worn rings for one reason or another.
