Thanks for the info....now whose dumb idea was it to put a tractor engine in a car? I kind of knew the Kubota governor was not suited to road use. After looking at the cutaways you sent, I see that the VW pump has variable injection timing. I can't find a drawing for Kubota. But the governor/pump is part of the engine casting and there is almost no chance of replacing it with an automotive pump. Kubota timing is adjusted by shims. I don't think it has speed sensitive timing. Like Briggs&Stratton has fixed spark timing. OK for a lawnmower.....
