It has the old style solid state coils. Has coil gap set at 10 thousands on both coils, has replaced plugs several times. I just looked at the spark plug on the weak side and appears to be wet with oil (not fuel). Had him recheck compression on both cylinders and both were 150-155.Is it possible that the oil ring is broken, but the compression ring is still ok allowing good compression, but oil to pass thru to plug.COMPRESSION ON A 25 COMAND SHOULD BE 165 MIN. WHAT WAS THE WATER MANOMETER READING?
