The governor works on centrifugal force (centripetal acceleration, tangential velocity squared divided by radius). Bearings could be dirty. If the injector pump control arm is near the stop limit screw under no load, the pump has and internal leak. If the exhaust is smoky, the timing is off or...

Interesting. Sluggish governor internals?

No, injectors are fine. The problem is the IP's control collar is binding, preventing the governor from calling for full fuel. Timing is fixed, only injection quantity modulates power. Being stored for 10 years without operation and using the crappy diesel varnishes the fuel system. And...

Joe, did you have to sow seeds of doubt in my mind over my 002a :shock:? I checked governor and control lever action, the latter was STUCK! And it is a major pain to remove. The governor's spring and centrifugal forces are slight, this lever must move freely. First, remove the stop solenoid...

If the injection pump is excessively hot, that is the problem. The pressure of the fuel multiplied by the volume of flow is energy, an internal leak in the IP will cause that energy to be dissipated as heat. Same thing as a hydraulic power unit if the flow under pressure is allowed to trickle...
