I can also see the valves rising when veiwed through plug hole and hand cranking the engine.I'm leaning towards this being a valve issue but just don't know how I get 95lbs, compression if the valves are bad.

Watch for ATF to leak out the carb or the exhaust. If it does then you know which valve it is that might be the problem. If it is a valve problem that is. Could also be the intake or exhaust port clogged in the block [Reply]  [No Email]

If ex too tight & not completely closing, that could dilute mixture enough to not fire. [Reply]  [No Email]

Going to try Old's suggestion with ATF,maybe one just ain't seating right??? Also going to try pressure testing radiator..thinking maybe an internal head gasket leak,no signs of it though???Thanks Dan [Reply]  [No Email]

Then it is back to spark issues. Could you have enough carbon around the valves to prevent fuel from entering and or exhaust from leaving?? A wet plug will indicate fuel entering but if your exhaust aint leaving you have a nogo. [Reply]  [No Email]
