Finally wired up motor to crank it over. Checked compression between 40-60 in all cylinders. Do you guys find a valve lapping and honing, new rings usually do the trick? Also this is a 51 m38 but I suspect it's a civvy motor. It's 24 volts but it came withe civvy carb and fuel pump...how can I confirm? Thanks

I think it should say on top of water pump the block boss there is a serial # starting w/ MC 123456 etc the motor mount supports are opposite one facing forward and one backwards buzzzzz
The only way to ascertain for certain what chassis Willys originally installed an engine in is the serial number prefix stamped on the boss above the water pump.
MB = Willys MB
V = CJV35
MC or RMC + Willys M38
CJ2A or J = CJ2A
3A = CJ3A & DJ3A
P = Pickup
U = Utility _________________ Wes K
