If you have had the cylinder off , and checked the valves, and
the piston hasn't got a big hole in it, it's not your rings! Rings can
get worn or broken, and still produce some compression. I would say THE
most likely problem you have is valve clearance. Face it, if the piston
is going up and down, and the valves are closing properly, you have to
have some compression. You have 47 cubic inches of air being compressed
on every compression stroke, so that air has to rush out somewhere
pretty fast to have 0 compression. I don't have a lot of experience with
this engine, but they all work on the same principal. I believe the push
rod length is how the valve clearance is set. They have hydraulic valve
lifters that take up the valve clearance when the oil pressure comes
up. My advice is, DO NOT buy a new cylinder and piston until you have
checked everything out thoroughly. I would lay a small amount of money
on it not being piston or cylinder, if there is no obvious gaping holes
anywhere. Ask around BEFORE spending large amounts money. Let me know
what you find.
