A few days ago, I had to quit using one of my H Farmalls 'cause the carburetor was running over. The float had obviously stuck, and gas was pouring out.
I cleaned up a spare carb and installed it. It would run great at any throttle setting from idle to full throttle, as long as the tractor was standing still. Put it in gear and let the clutch out and it would stall from fuel starvation. Step on the clutch and hit the choke and it would take right off again. Double checked the hookup from the governor, and tried adjusting the power valve. Loosened the gas cap. Nothing changed. Pulled it off and double checked the float setting. It was OK.
I then boiled the original carb, checked the float valve, and re-installed it. Same thing, gas pouring out.
Took the other carb apart again. Checked the float level and idle and power valve settings. Book says initial setting of 2 turns open on the idle screw and 3-3 1/2 turns on power screw. Put it back together and put it back on the tractor. No change. The fact that the engine rpm follows the throttle from idle to full throttle tells me the governor is hooked up properly.
One thing I haven't checked is the screen at the sediment bowl, but from the way gas was pouring out with the original carb, I doubt that there's any obstruction in the sediment bowl screen.
That's where it sits right now. Runs great through the full throttle range, but put it in gear and let the clutch out and it stalls. Step on the clutch and give it some choke and it takes right off again till you let the clutch out.
I've done enough of these that I don't think I've overlooked anything, but I must have.

In the summer of 1995, my father, Russ Goodwin, and I acquired the 1945 Farmall B that my grandfather used as an overseer on a farm in Waynesboro, Georgia. After my grandfather’s death in 1955, J.P.
