MooneySpacers,
I just had my propellor overhauled after an annual inspection because it was throwing grease from the hub. I got two used blades because mine were no longer serviceable. After install, my engine tops out at 2550 RPMs. We looked at the governor and noticed that it was adjusted to its stop of high RPM. I had the governor flushed and tested by two shops and they both confirmed that the governor was good. I had it overhauled anyways because I cant tell when it was last done. Put it in and got the same 2550 with the governor adjusted to where it should be or adjusted out to the high rpm stop. I took the plane for a lap around the field and saw 2700 rpm on climb out and around 2685 on downwind. We had a prop strobe tach with us and it coincided with the tach in the plane. I'm having my A&P check the fuel pressure and fuel flow today. We also measured the blade angles and and they were within specs of the TCDS...
Any advice on what I can check next would be great fully appreciated.
Thanks much,
Jon
