Old Pokey, Before you start turning screws, I would try bumping up the governor spring. Unfortunately, I don't know exactly how to do it, but from your symptoms, it sounds like your governor is not sensitive enough, even though it may deliver plenty of fuel. I've been told by pump technicians that for combines the MW governor spring needs to be set much more sensitive. We had one that needed 6 additional clicks on the spring, which was the "worst he had ever seen". When you get it up high enough, it may be a bit unstable when the engine starts, but smooth out in about 30 seconds. This won't change the fuel delivery, so it is safe. It just lets the governor kick in at a higher RPM so that you reach max HP at a higher RPM, which is what you need in a combine. They probably set your governor like a tractorIJ I've been told that you can click the spring up while the pump is on the engine, but I don't know the details. I'm guessing there is a cover to take off, then you'll see a lever with a series of notches. The governor spring will be hooked in one of the notches. I think you need to go closer to the pivot point of the leverIJ
