Just like with your stock dizzy. #1 tdc compression, line up your timing tab and balancer at zero, point the rotor at #1. Rotate the dizzy about 1/2 inch ccw. Lock it down.
Should fire up.
Check and set the timing after it's running.
Try 14 initial to start with and adjust for what your motor likes.
Is this a rebuilt or just a repainted/detailed motor?
