Well we got the old girl running. Turns out my uncle had run it til it ran out of fuel and just parked it. So the tank was dry, but there was still fuel in the rest of the system. We flushed the tank, put clean fresh diesel in it, and then bled it step by step to the injector lines. Fuel in the lift pump,fuel filter, and injector pump was still clean. Of course, in the process we found that while he had had the tractor he had fried the solenoid and broken the starter engage button on the front of the starter. A jumper wire solved this temporarily. Once we got her goin, WOW! She ran smooth with no hiccups and once warm, ran all through the rpm range with no stutters, farts, or any wierd noises, AND NO SMOKE! Hydraulics work, transmissions both work and the alternator charges properly. Lights and guages don"t work, and the return for the auxillary hydraulics is cracked, but those are problems for another day! Gonna change out all the fluids at Easter when we"re out there again.
