All V12s are not the same.

The starter was missing on this engine. Picked up couple from junkpiles. Starter drives were too short and sit too far from the ring-gear. Measured about 6-7 and they were the same. Finally measured flywheels, mine was 16 1/2" diameter, and for a double disc clutch, the rest 15 1/2" and for single disc. Had to spend the day changing the flywheel and housing, so the small starters would work. No telling what this engine was originally built for, and ended up new on a pump.
May get to test spin on starter tomorrow, but still have to rewire around the safety switches, put propane kits in carbs, and other odds and ends before the big crank attempt.
Just hope I got all the water and oil passages cleaned out. Glad I have alot of junk motors to rob and farmers will let me do it. I think they are just wondering if this thing will ever fly,-- I am too, but it's fun.
One bolt at a time, then do it again-
