Assembly starts now. Do not jump ahead:
Put the cable into the socket of cam cover. Leave the other end of the cable on the floor.
Gently work the 'T' of the cable into the claw of the worm. Turn worm in cover to make the 'T' installation easier.
Bolt the cover to the motor.
Grab the lever end of the cable and yank on the inner cable. The worm should operate in the cover. The clutch won't operate because the screw, dust cover & locknut isn't installed in the worm yet.
WHEN YOU RELEASE THE INNER CABLE, THE SPRING NEEDS TO RETURN THE WORM TO THE PIN. If not, check for clutch rod dragging inside the worm hole and fix. If OK, then it's a cable problem. Fix the cable.
Route and anchor the cable in the operating position and totally hook the cable up to lever.
HANDLE BARS STRAIGHT AHEAD FROM THIS POINT ON. this gets overlooked too often. work lever. spring should return worm to pin again. if not fix cable more.
With the lever against the perch, adjust the perch adjuster one turn at a time until the cable lifts the worm off the pin. Then, work the lever again. The spring should return the lever completely to the perch. If not, fix the cable more.
Pull & hold lever to the bar. You should be able to lift the adjuster from the perch. If not, it's because the worm is hitting the sprocket nut, lock tab or sprocket. Repair the problem.
At this point, the worm swings thru an operating arc without contacting anything inside the cover. Pin, nut, locktab and sprocket.
Adjustment #1 is complete. Do not change it.
