Doc - I admire the can-do attitude. Post a pic of the whole sled with the rebuilt engine installed. - Deerfield

More than likely the rave valve is worn and traveling too far,thats what grabed the rings and caused the piston failure.

That makes some sense as the middle of the valve is chipped. I didn't think the rave valves could travel too far, I will have take a close look at that one

Last night I went in to the shop manual then poked around the engine and found that the TB throttle body to intake manifold rubber boot clamp was not even secured. I could rotate it around the port on the PTO (power take off) cylinder ( the one fried) . On the MAG cylinder (closest to the magneto) the clamp was not tight as well. I bought the doo 3 years ago so I have to think it was like this all the time and I was lucky to have it last this long. So I think with the air leaking in thru this could definitely caused a lean condition and destruction of this cylinder. Contrary to mike above the rave valve cant travel further into the cylinder as it wears imo as there is a definte stop.

Rave valves were ground back at shop for oversizing of cylinders. I think I'm going to take a little more off the middle of the pto cylinder rave as the clearance does not look as much as the rest of the valve.
