Joe, What kind of lube have you used so far? I use a mix of diesel fuel, Kerosene, and marvel mystery oil. Put it in each cyl and let it soak for a few days. Then I spray PB Blaster in each cyl and let it go another 2 days. Then I put a socket on the crank bolt and try rocking it back n forth. Use that in conjunction with the air pressure. Should get it done. Davis JOE FULTON <piper_pa20@xxxxxxxxxxx> wrote: Well I tried the air pressure trick on the aluminum 196 this morning. No 3 and No. 6 cylinder had the valves closed so I used the spark plug fitting from my compression tester and screwed an air hose nipple into it. (No welding Don.) My calculations showed approximately 700 to 800 pounds of down force with 100 psi air into the cylinder. Still no joy. Nothing even budged. I have rocked the starter using a new battery just to make sure the starter was not locked up. With the air pressure applied to No. 3 the engine JUST visibly rocks when you also engage the starter. I'll leave the pressure on the engine a few hours and see what happens. I'll work on the Gremlin today and maybe fool with the 196 engine some more tomorrow.
