I am stuck with a running problem on my Farmall H - starting running rough and cutting out end of last year. Working on it this spring I have check what I think are the most likely issues -
Found rear manifold slightly loose - tightened - no change - replaced studs/gaskets/torqued - no change
Insptected tank - installed in tank screen/replaced screen and thoroughly cleaned fuel bowl - confirmed good flow to carb - no change
Removed/cleaned/rebuilt carburetor - the inlet screen on the carburetor was clean when removed - set idle and fuel jet to factory settings - no change
Fires right up with full choke - runs smooth at 75-80% choke - move choke to 50% and the engine will immediately start sputtering and die - move to 100% choke and the engine will sputter and die - the tractor will immediately restart at full choke (some fuel will drip out of the weep hole) - set to 75-80% choke and it will run.
Any guidance would be greatly appreciated
