M20F Static RPM


Recommended Posts

There are several possibilities:

1. The tach reads low

2. The prop cable isn't reaching the stop

3. The governor is set low (it shouldn't be governing at all until there is some airspeed)

4. The prop low pitch stops are set incorrectly

5. The engine isn't putting out rated power

Welcome aboard blank!

That has to be one of the crummiest first posts ever… :)

Cam lobes are important…

Engines have a hard time producing power when they can’t breath…

 

Did you get this challenge fixed already?

Or are you still searching for next steps…?  (Cut and paste this one…   :()

PP thoughts only, not a mechanic…

Best regards,

Thanks. My overhauled engine with DLC cam is being delivered today; can't do anything with it until I get my governor back from o/h next week.  No sense to install the engine without the governor first and then fight with it to put it in next week.

It’s outstanding that you were able to source DLC lifters.  Thanks to Aircraft Specialty’s outstanding young parts man, I got a set barely in time for reassembly.   I believe it is the next best thing to a roller cam and maybe better in some ways.
