I’m a new member so I hope I’m doing this correctly I just bought a 81 m35a2 runs and drives like a top just won’t hold a idle have to keep it running with the foot throttle or hand throttle Found a lot of info on here to get me to the point that I am fuel shutoff lever moves smooth but is springing back to 5 o’clock when throttle is let up I believe it has to do with something in the governor housing can I remove the housing without taking the IP off or do I need to remove it as one unit
