The engine on the John Deere speedster I posted photos of here a couple of days ago is a two cylinder flathead with an updraft TSX carb. The engine originally came from a small pull type combine or small tractor, and thus has a governor which I have hooked up. I was showing it to my mechanically inclined BIL and brought up the possibility of disengaging the governor and hooking the accelerator pedal directly to the carb throttle valve in a more car-like fashion. He told me if I do that, with the updraft carb with no accelerator pump, I will be killing the engine frequently because it won't be reactive enough. Is this true? Photo below show the engine in its natural state.
