philipdltx18,

I'm confused. The flywheel is keyed to the crank. If you had #1 at TDC and the pointer on the ball...and the truck started and ran, then all is as it should be.

As Jim Meier noted, things can be 180&deg out, BUT, the truck wouldn't start! You said it started, so it isn't 180&deg out!

Why isn't the ball where it's suppose to be..I don't know. Some important fact has been overlooked. When you put a light on #1 plug wire, the ball must light up, that's the only way this engine operates.
