I just finished doing what everyone suggested: Took off carb fuel bowl and checked throttle plate; not loose and closes with no binding; checked tang on throttle shaft; it is connected to carb and works freely; Adjusted equalzer on bellcrank so that throttle plate would close;all good; checked with disconnected linkage; couldn't see and problems; checked movement of entire linkage with throttle handle; seems to work fine. Started tractor with throttle handle closed (and also throttle plate) tractor raced so shut down immediaely. Where do I go from here: Governor lever seems to have "spring " in it, altho not strong. how can tractor run so fast with closed throttle plate unless governor is doing something right after starting. Appreciate any advice. [Reply]   [No Email]

If the gasket is bad and doesnt seal it will suck air past it and the tractor will race. It basicually takes the throttle away from it. It will suck the air and it will pull the fuel up out of the carb. Check that first it is the cheapest and easiest. Good luck Jason [Reply]  [No Email]

I disconnected the linkage to the gov so it would come all the way forward and it ran great. Someone had the wrong linkage in it. I made one that was correct and fixed the problem. They had removed any adjustment rods in all of the linkages. I used some smooth rod and threaded the one end and used a yolk that I had lying around and was all good after that. Just a thought.

No such luck. The weights and spring tension balance out to control speed. Harder the spring pulls on internal lever, faster engine will run. That link vertical adjustable link is to be adjusted so when gov weights are fully collapsed the throttle plate in carb is fully open, straight up and down. To adjust, take pin out, pull throttle lever wide open, pull up on lever that goes to carb, and then adjust the length of the rod clevis so pin just fit in. [Reply]  [No Email]

The spring should be the only thing opening the throttle shaft. Are the weight "fingers" engaging the proper area in the gov? [Reply]  [No Email]

Took top cover off and held down the rod goin to gov and she idled right down. When I held it down, it took all the slop out of the linkage. The stop nut on the rod was only down about 3/8 of an in. I'm assuming the rod is adjustable since it has a lot of threads on it. Someone was in there before. There's a brand new cotter pin in the pin that holds the throttle shaft. Could it be that whoever worked on this didn't adjust it correctly? [Reply]  [No Email]

It is a simple procces. But a little hard to tell how to do here. With a manual it show what parts are what and what order to set every thing. I just did it to my 650 Gas and with it done by the book it all works right. From what I have read here everybody is kind telling you parts of procedure, but not everything at once. Get the book if you don't have one start from scratch. [Reply]  [No Email]

Don't know why I didn't consult it earlier. I just went thru the adjustments shown in the manual, but it didn't come out exactly the way the manual says. For example, the clevis on the gov. rod was already adjusted down as far as it would go, and should go farther to line up with connection with throttle shaft. It supposed to be adjusted with WOT. I got as close as possible to what manual says, and actually got the engine to idle on its own for about 5 minutes, but then it started revving up again. Almost acts like the governor is sticking, but WHAT is sticking, I don't know. [Reply]  [No Email]

One additional thing: when I was trying out the throttle linkage, i found that there is no resistance when putting in wide open position. Does that indicate a weak spring? [Reply]  [No Email]

I think I have replaced that in every single Farmall H and M I have worked on through the years. The 1951 H I rebuilt in 1999 (article is on this site) took off like a scared jack rabbit when I started it after the rebuild. Got broke in real quick!! [Reply]  [No Email]

I just took off the governor plate and found that the set screw (bolt) on the speed lever very loose. Tightened it up and used a new lockwasher. Restarted tractor but it still speeded up. BTW, The whole gov. assembly seems very "relaxed" (including spring) when throttle is in closed position. Is this the way it's supposed to be? I reread your article on your 51 H and you mention adjusting the "High speed bolt" Which one is this and which way does it turn to lower rpms? Thanks for answering. [Reply]  [No Email]

The lower bolt is the high speed bolt. Screw it in to slow down the engine RPM. I am guessing around 1/2 inch should protrude left beyond the lever assembly. Upper one is the idle speed about 3/8 inch protruding. Should get you in the ballpark. [Reply]  [No Email]
