One ninety gas governor

Before disassembling anything, let's give the external parts a good look over, some lubrication and then proper adjustment. For the record, the 2000 series gas engines just didn't have a very good governor, as compared to other Allis engines and even some competitors. Maybe when they were brand spanking new, they were just barely OK, but under 2000 RPM I always felt they were very lazy and disappointing. So, check for any looseness in the carb throttle shaft arm to the shaft itself. If the spot weld or crimp has loosened up, you could be losing governor action right there. Also, inspect the ball joint on the link rod attached to the carburetors arm for any looseness. Spray some WD40 on the governor spring to reduce any friction between it and the plunger inside. Sometimes a little alignment tweaking is needed to prevent dragging of the governor spring with the parts it fits over. Lube WD40 the ball joint on the end of the link rod too. Lastly, place the throttle in the wide open position (engine off) and remove the clevis yoke pin on the governor's vertical arm. Use the threads on the yoke to shorten the link rod so it is about 1/3 of a hole short of opening the carbs throttle shaft 100%. This is critical to good governor action. Once you've done this try it out and see what you think. There is no governor "KIT" for those engines. One piece at a time if they are even available. These engines don't explode governor weights like a D-17 does.
