Seller has not tried to start it. Only 17 hours is shown on meter (but does the meter work?).

“PE-95-F motor generator with Willys L134 engine. 17 hours on the meter. The oil in the crankcase is clean and clear. I have not tried to start it. It uses a 6 volt battery for starting and running. The generator is an Onan 10kw and very heavy. My plan was to use the engine for a jeep project but it might have a better purpose for someone else. A website: radionerds.com has the army technical manual (TM 11-904) for it”
