As Jack said, the governor seemed the easiest to change out, and inexpensive, so we did. yesterday morning. After verifying that all seemed to be working correctly, that it stopped at 120, and kicked in at 90, we headed out.
after 1 1/2 hours of highway with some traffic stops, we arrived at our expected destination without any issues, other than the darn oil leak coating the rear, front of the toad, and Florida highways.
Clifford, we are pulling the whole thing out, engine, transmission and all and fixing the oil leak. while we're there, we're going to change out any hoses, wires, cable, do maintenance on what may need it, and paint everything so it looks brand new again. And clean up all the caked on grease, oil and dirt on the surrounding bus. at least, that's the plan
and for those that don't carry one now, you might want to invest in a decent air compressor to keep around for the occasional bus air failure. mine is carried back by the engine, so my 50ft hose easily went across the bay to the air connect, and the extension cord hanging out the bedroom window worked. saved us probably getting towed to some garage where they would have charged a couple hundred bucks to change a governor by the time they tested it.
