H idle to wide open throttle and belly pump issue

Hi all, got an H i'm working on after the owner could not get it to run. put gas in, and wow, it runs, BUT when going from idle to WOT you have to go pretty slow or it will die, like lack of fuel maybe? or is that a timing issue. took carb apart, cleaned it up. idles great, WOT great, just going from one to the other.
also noticed the rear seal of the belly pump, where the trans shaft comes through is leaking. can i change that in the tractor by removing the coupler?
thanks
Gary

You can change out that seal with the belly pump still in the tractor, but it is so much easier if the pump is removed. Well worth your time to do it.

Farmall Hs are rather cold blooded, and the hesitation MIGHT be just because the engine is not warmed up enough. If that is not the case, then I can recommend making sure the carburetor high speed idle adjustment screw is a minimum of 3 turns out, and if that does not help, then there is still some crud hiding deep down in the carburetor.
 
You can change that seal, but need a way of holding the shaft from turning while loosening the adapter for the coupler. I do not know how, so let me know if you get it.

The pump is HEAVY, put a jack under it and get help.

I made an adapter that let me use an air impact to remove the coupler shaft. Might be another way, but the impact seemed to be the quickest solution.
 
As to Hs being colds blooded, I got to disagree. My H starts faster than anyother iv ever seen. BUT, It has a dang high idle I havnt been able to get rid of.
 
If your carb is really clean and jets are adjusted, I would make sure your governor is also really clean, and the weights are not sticking. you could have an accumulation of old oil turned to dry gunk in the governor. before tearing it apart try some penetrating oil and degreaser on the shafts.

A dirty, sticky governor would exhibit totally different symptoms. Don't think the governor has anything to do with it.

"Cold Blooded" does not mean it is hard to start. Cold blooded means it will sputter, miss, and almost die if you attempt to rev the engine BEFORE it is warmed up.
