Thanks for the suggestions. I did not touch the cam at all, in fact the engine had never been opened up since it left the factory (I am only the second owner and I know the first owner well). I checked my feeler gauges, just bought the new set last week, with a micrometer and they are spot on. I had to do about two full rotations of the adjusting nuts to get them down to the right clearance, I figured the new valves were slightly shorter than the old ones. If I back off 1/4 turn to about .030 clearance I jump from 100 to 150 psi. The tractor ran well before the "operation" but it was getting a little hard to start and there was some blowby but it had power and ran well. I see no way the cam could be off time because it was running and not making any weird noises. Maybe the IT manual is giving my the wrong clearance. It says .017 and .021 (intake/exhaust) anyone have a Ford manual to check?
