Super H Governor

I have a Super H -Stage 2-and I can not figure out the high RPM's that I get when I start it up. When I start it up, it opens up to full RPM's ----no idle can be obtained. I have looked at all the info that I can find on this forum regarding governors, and nothing seems out of order. I have compared the governor on a Stage 2 to the governor on my Stage 1, and they both appear the same. I put in a new throttle shaft from the governor to the carburator. I switched springs from my Stage 1 to the Stage2. Both springs reacted the same on the Stage 2. I have lubed all parts in the governor and checked all the linkage to the hand throttle. All items compare to the Stage 1 Super. The Stage 1 operates just fine. The fly weights are not loose or sloppy. The sleeve on the governor shaft slides easily and all the parts are free. I appreciate any ideas or suggestions.
 
Common problem, the rod from the carb is not connected to the gov properly, happens all the time, a little hard to see when assembling, but you need to do it again. I'm surprised you didn't come across that in the archives, there are many posts about that. UNLESS you know what I am talking about and have checked it.
 
I have checked the rod several times, and it is in the notch. Yes, it is difficult to see, but I have taken all precautions to get it to fit properly.
 
It is hard to tell from your description of the gov problem weather you changed the cross tube linkage between governor and carburetor before or after your problem developed. If you changed it , and then the problem started you no doubt have missed the alignment notch between carb and gov. If it was present before you changed it and you changed it trying to overcome the problem, well, then the butterfly in carb is loose or missing a screw and not closing. If I was there I could tell in an instant just by looking at the linkage and feeling it with the pin out hooking gov to cross tube .
 
The problem of high reving was going on before I switched cross-tubes. The carburator had been taken off, cleaned, and a new carb kit was installed. This was done by a reliable mechanic, but I did not inspect the butterfly for a loose or missing screw. I will check it out. Thanks!
 
If carb checks out ok, look at the thrust bearing in governor. If it is completely shot the weights will not be able to move internal linkage far enough to close throttle, however, this does not usually bother at lowest idle positon of throttle lever provided spring tension can be completely relaxed. In low idle you should contact internal stop in governor and spring should hang loose.
 
Check the thruster bearing. It should slide on the upper shaft but not wiggle. Had the exact same problem when I rebuilt the 1951 H in 1999.
 
I had the same problem with my Farmall H, caused by me. I failed to get the tab on the end of the governor shaft located correctly. The butterfly stayed open and no idle could be obtained. The tractor started very easily, but the engine speed was savage!

Others have covered most of the potential issues, but to get back to the kiss principle, have you checked the idle speed adjusting screw to make sure it is not turned in too far? I mean the one on the carb.

And while you have it back off checking the throttle plate, check to see if the butterfly will even close. If the plate is in the shaft backwards, it will sometimes prevent the throttle from closing some or at all. The plate is not round, but somewhat oblong. A very difficult thing to notice if you are not looking for it.

If the tractor was idling fine before the rebuild, then I would say the gov is adjusted correctly and issue is in the carb or the linkage.
