Have an IO-520 that the prop wont cycle completely. put another old prop governor on it and it got worse.
I just dug up two more governors, but if neither of them work, I have to suspect the transfer collar inside the engine. Been so many years since I've seen this problem, but I seem to remember that there was a way to check the collar with pressure. Any Ideas before I have to pull the engine apart??
