Re: No compression
We just had a club members 29 coupe like that. The compression was all over the place and varied from test to test. Some days it was ok then some days it wouldn't start. Finally we took the head off and them the side cover and what a mess. All the ports, valve stems and guides were coated with a thick layer of carbon goo like molasses. We removed the valves, guides and cleaned everything including the ports. Then lapped the valves reinstalled everything and it purred like a kitten as they say.
