So I've been on a couple tractor rides as of late and I'm having an issue with the tractor speeding way up when going down hill. I have noticed in 5th gear the governor and motor seem to have some effect
in slowing the tractor down going down hill, but usually I'm pumping my brakes and trying not to hit the guy in front of me. Mind you I try to leave a large gap before heading downhill. As for going
uphill I have almost no issues, you can hear the governor open right up and away we go. I have never experienced any "surging" in the engine, as mentioned in the service manual, at idle or any other
time.
I have a Farmall M, wide front with one set of rear wheel weights (no fluid in the tires as they are 3 weeks old).
Here's what I've done:
1. We checked the compression on the engine this past winter and it tested a couple pounds below what it should be in each cylinder
2. Rebuilt the carb this past winter and then set it based on what I read in my service and owner's manual.
3. I have checked and rechecked to make sure the tube from the governor to the carb is hooked up correctly.
4. I opened up the governor and all the parts appear to be moving freely and I didn't notice any slop in anything other than a bearing on the center horizontal shaft, with the bearing being towards the rear (carb side), seem to slid a little on the shaft.
I'm at a loss as to what to do to help correct this situation. My guess is it's probably time to rebuild the engine. Any other thoughts or things I may have overlooked? Thanks
