Hello all you wonderful Lister gurus!
Regarding my 1976 Lister ST3/Kohler 12Kw enclosed trailer-mount gen unit.
Our local PoCo was out replacing a pole yesterday so I fired up the ol' genny and ran the house during the work.
Started fine, ran smooth, never even winked at the load, so I went about doing my thing. After about 2-2.5 hrs, it shut down! Overheat switch closed and opened the safety relay. Engine was REALLY hot! This morning, I checked the oil and found it to be WAAAAYYY overfilled and diluted with fuel. When it failed, it was a cool day and the load on the system was very light.
Not sure where to begin diagnosing, is there anything I should be looking at? I suspect possibly the mechanical fuel pump may be a source of the dilution, and I hope I didn't smoke the cylinders with the poor lube!! Tried starting it after a couple hours of cool down, but it wouldn't crank, tried to, moved some. This model uses the gen as the starter, it tripped the Klixon overload protector!
Thanks in advance, as I know there will be lot's of good advice coming my way, y'all ROCK out there!!
