os 48 compression loss
Bill:
I experienced compression loss on an os 48. It came on suddenly.
It must be related to the intake valve not closing. With the valve cover off, if I add finger pressure to the push rod side of the rocker arm (I hope that's what it's called), compression is restored. This may last through several manual rotations, quite a few if you do not tip the engine from the vertical. Tipping the engine triggers compression loss.
Something in the cam???? (This engine has 13 seasons of use). Thanks for your time.
