Hi, does anyone have instructions on adjusting the governor on my H, the engine is surging and I know there is a lot of wear on the governor Maybe this winter I will bore the holes and press bushings in the bored holes with new pins but I'd like to have it run good for the summer, thanks alot
 
Its the only tractor I own that I doesn,t have the operator and service manual yet, And I was thinking of it being too lean but if I open the main jet more it will start to smoke black the tractor runs great idle and full throttle but tends to surge in between, rebuilt the carb, new plug wires, condensor, coil, plugs, rotor, cap etc. thanks alot guys have a great day
 
Maybe this is no help. but it might be. This is how I adjust my "H" carb;
Make sure the float isn’t sticking or touching the insides of the float chamber. Some previous advice was to use a Dremel tool and smooth the insides of the float chamber so it doesn’t rub or touch. Pretty important. Set the float so the top of it rests 1 27/32" above the flat surface of the float chamber.
Initial settings are as follows to get it started;
Main fuel adjusting screw, big screw facing down at an angle, towards the rear, at the bottom of the carb; 2 1/2 to 3 turns open. This main screw turns clock-wise for leaner mixture.
Idle fuel-mixture screw, smaller screw facing forwards, on upper left-hand side of carb; 1 to 1 1/2 turns open. This idle screw turns counter-clockwise for leaner.
Idle speed screw, faces outboard, at the top of the carb; set for 450 rpm, and make sure the governor correctly engages the slot.
Final settings are determined as follows;
Get the engine warmed up, and idling.
Turn OUT the idle fuel-mixture screw until rough running, then turn in until it idles smooth. (Mine is set at 1 turn open.)
Rev it up, wide open, warmed up, then turn the main fuel adjusting screw IN until rough, then out til smooth, then 1/4 turn to 1/2 turn further out. (Mine sits at 1 turn open. Other advice has been to set it at 2 1/2 turns open for pulling implements.)
Should rev up smoothly and evenly.
Too Lean = stumble, sputter, damaged melted plugs.
Correct = tan plugs.
Too Rich = back smoke, black sooty plugs.
 
Thanks, Well I adjusted the carb last fall almost exactly as you did and the spark plugs are a light brown color so I guess I am ok on that side, I tried adjusting it leaner, richer, seems to help on the surging having it richer. I also tried playing with the timing of the dist but doesnt seems to make much difference, Thanks
