Yall want the good news or bad news. Well good news is ibdid a compression test today. Bad news 3 outa 4 cylinders held 0 compression. An number 4 cyclinder had just over 75 psi
3 out of 4 have 0 compression.... Interesting !
So... when you put your finger over the spark plug hole and crank the engine, you feel absolutely nothing ?
Have you tried a simple leak down test?
1. loosen the valve adjusters to close the valves entirely on their seats.
2. Make sures that both valves are closed.
3. pump compressed air into the cylinder thru the spark plug hole.
4. Listen for escaping air.
5. the sound of air coming out of the exhaust means exhaust valve isn't sealing. The sound of air coming out of the carburetor means that the intake valve isn't sealing. The sound of air coming out of the crankcase means the rings are not sealing.
A pretty simple diagnostic test to let you know what needs to be fixed before tearing the engine apart.
