Hi all!
I have an MF40/135 tractor. It is the 3 cyl Perkins gas engine. I just rebuilt the carb, installed some new jets, and the timing is done to spec. In neutral, it idles great and I can take it to about 2200-
2300 RPM which is what spec said it should be when at 27 degrees before TDC. When I put it into gear and then release the clutch it bogs down. If I am on flat, and throttle up, the RPM will eventually move
up. If I am trying to go uphill, it loses power and drops down to sub 500 rpm. I put the brakes on, push in the clutch, the RPMs climb and then it will go forward a bit and drop back down to under 500.
When parked and in neutral, I brought the throttle up and watched the governor. The governor moves towards the radiator. However, when running and under load, the governor doesn't appear to be moving around
in relation to the RPM/load issues.
New plugs, wires, coil, alternator, and starter rebuilt. A little blow by coming out of the valve cover vent, but nothing to scream about. Does this sound like a governor issue or is the engine still not
getting enough gas from the carb or something else?
