I thought I would give an update. I just passed over 110 hours on the generator now. it only gets run when the power goes out. the cyl head still weeps coolant even with a new head gasket. It is a small amount and I don't really worry about it. The power went out yesterday and the lister ran the whole house ( all lights tv, computer, coffee pot, well pump, fridge, beer fridge, other beer fridge, freezer, washing machine, wood boiler circ pumps household of 6) for 23.5 hours and used just over 5.5 gallon of diesel. that is a fun statistic for you.
After such a good run I was looking things over and noted that the mice had moved into my spare parts. When I bought this engine from Gary at DES I bought a whole complement of spare parts. Piston, rod, bearings, bushings injector, injection pump ect... ect… the mouse urine is very corrosive and was damaging my spares as they ate the cardboard. So all the spares had to get unboxed cleaned and moved into steel ammo cans. I painted them with fluid film as I put them away. Other that that it has been great.
