No pics, but I imagine these engines aren’t too common?
“Army mule engine. Four cylinder air cooled Willys apposed. Was used on the Vietnam era Army Mule that was used to haul a big recoiless gun into the countryside. The Mule was an all wheel drive vehicle one driver seat.
It has the clutch and pressure plate. Home made electric starter and hand cranked. The original vehicle has the starter on the transmission and that is missing.
Runs excellent.
