Ok, so I got the ring in, and put 40 oz through the engine, and the thing is still a dog with very little copression. so little still in fact that sometimes when you start it by hand it won't even pop through all the way around, but stop at TDC.

The engine had a lean run in the air where the eninge shut off, and I'm guessing that did more damange than just to the ring.

Right now it will spin a 12-6 K-series MAS at only 11700, My buddies 55 ax spins that, so I'm guessing this thing is toast.
