Well, here’s the carnage. What ever got into the cylinder must have been a piece of aluminum. It tore up the side of the piston a bit and seems to have melted and fused it’s self to the cylinder wall. It got into the ring lands and locked the rings in place. What I thought was a gouge in the cylinder wall was actually a raised ridge on the cylinder wall. It was whatever got caught in there. It came off with a little sanding with some emory cloth and the cylinder looks like new yet, no scratch or gouge at all. With a new piston and rings I think this motor might be good as new.
