turn dist till the magnet is lined up with the nearest tooth & at that point see if the rotor is under or near under a cap terminal (checking rotor phasing) & holler if it ain't & if so how far off is it. If all good there turn the dampener to 20 BTDC #1 compression & come up on it clockwise to take slack out of the chain. Turn dist till the magnet is lined up with a tooth. plug in #1 plug wire in the cap terminal above the rotor & finish the rest of em around in order. plug the vac advance nipple on the carb (for now) so its disabled. fire it up
