and retainer plate to lock the cable in position.

AH075

„

NOTE: The round part of the cable end must

come through the hole in the plate. If it doesn't, the
cable isn't assembled to the piston valve correctly.

12. Thread the plunger cap onto the choke cable. Place

the spring over the cable end and compress.

Position the cable end into the starter plunger and

release the spring.
