: 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 agree with the others - it sounds like a partially plugged fuel line. I currently have the same problems on my wd45 after getting it started after it was stored for 6 yrs. Junk in the tank keeps plugging the fuel intake at the tank. I'm going to take the tank off to clean it out.
