: : : : : My Allis Chalmers D-14 hadn't been started all : : : winter, so I drained the fuel, and replaced with : : : fresh gasoline. New plugs, points, cap, rotor, : : : condensor. I also converted it to 12 volt neg : : : ground. So it also got new coil and ballast : : : resistor. I cleaned the oil-bath air : : : cleaner thoroughly, and refilled with new oil. : : : It starts great and runs fine. As long as there : : : is no load on it. After putting a small load on : : : it (just driving it) the engine will start to run : : : rough, then start surging. It will speed up, : : : then slow down. To the point of jerking back and : : : forth. Anybody have any ideas? I'm stumped. : : : I've never had problems with the governor before. : : : Maybe it's not the governor causing it. Any : : : suggestions would be greatly appreciated. : : ::::I would guess that it's a fuel problem. Just enough fuel to to idle, but not enough to pull a load. Check the flow from the tank to the carb. if this is good, pull the carb. bowl and look for gum, sticking things up. : : :::Bonehead : When I read this I thought of either a vaccuum leak, a stuck needle valve, or something stuck in the timing. I think Mr. Bone is right tho. Me
