M920 Engine RPM retarded
I am still working on getting my newly acquired M920 on the road. The problem I am working on now is that the engine rpm's won't go any higher than about 1900 rpm. I have been looking for information on the engine governor in hopes that it might point me in the right direction. Any ideas as to where to start looking to solve this problem?
We also just got an M920 in for the Military Museum of Texas, and are having what might be a related problem. With engine in neutral, engine revs up just fine. However, when you put the transmission in gear, the engine doesn't rev up at all???

Have you downloaded the TMs for the M920?
According to the TM 9-2320-272-10 the max governed RPM is 2100

M920 Engine RPM
I had a typo in my original post. It should have said that max rpm I am getting is 1200.
I have all the manuals (except for the one on the engine), but I can't find any reference to the governor.

Here is a link, should cover everything you are looking for, if this does not fix it you have a clog in either the fuel filter or the pump.
