Sheared flywheel key? Sure sounds like it. That's what happened to my go-kart engine when I didn't tighten the flywheel "Nut" enough.
BTDT on the ring issue on a B&S engine too. Did a rush repair job on my tractor some 15 years ago. Conn rod bolts came loose somehow & piston was slamming head. Piston was shot. Bore was OK, but a little worn. Put in the 0.020 piston with matching chrome rings. Didn't hone or anything since I put the chrome rings in. Lasted at least 8 years after that. I would assume it's still running for the new owner. It was a 12-month tractor, with a 48" mowing deck in summer & 48" blower in the winter.
