You can get a new governor cover at your local diesel shop, or if you're lucky...in the junkyard. Again, I would make sure I had the slight spring action when the new cover was pushed back and forth on the pump. Don't force anything. I got into trouble by bending the arm internal to teh cover...gave me my almost fatal runaway condition. The be sure you have an audible "click" key on when you remove and replace teh FSS wire. AS a precautio I would follow waht Zigg said and take that air intake screen loose and have a smooth clipboard or piece of clean plywood to hand just in case it starts to take off when you start it abck up. You do not wnat runaway that is really scary. The rust in teh governor cover tells me you have gotten some water or chemical nasties in your WVO. That stuff is often bad by the time teh restaurants throw it out. That is why mine always gets converted to biodiesel, washed, dried and filtered several times.
