drewleroy, first thing you do is look at the rear of the injection pump. If there is a vacuum tube from there to a box just upstream of the intake manifold (and no where else) then you have a pneumatic governor. If you have it and you have a gorilla knob (push/pull switch to left of steering wheel used to glow, start, and stop the engine) then you're in luck and the troubleshooting is pretty easy with a helper and a hand vacuum pump. You won't need to start the engine to check throttle linkage, governor, gorilla knob or linkage. Suspect an internal oil leak after the first three. Let us know what you have so we can get you started. I go away in a week for three weeks to climb smoke stacks.
