Oh man! You using Sal for the cylinders? Your mechanic should have a calibrated orifice to check compressions. Continental says that compressions to 40 should be okay and that the combustion chambers and valves should be checked with a borescope when they're low. Any good A&P and all A&P's with IA should have a borescope.

Checking compressions... 79 ! , 79 ! , 79 ! , and ... (drum roll) 59 and the noise of air escaping through the exhaust. : - ( Tried staking the exhaust valve. No success. Had to pull the jug. Called the guy who overhauled them 1 1/2 years ago and he said to bring it over (Saturday afternoon), that it probably was a stuck exhaust valve and it should be ready Monday afternoon. Can't complain about his response!! Another sour note is that we pulled a helicoil out on another cylinder when pulling out the spark plug. Something else to deal with. Well, as I used to tell my son: "Patience is the mother of happiness" Now It's my turn to apply it. Eliacim .
