6. Insert the choke shaft with lever through the choke tower (Fig. 6). Make sure the choke shaft with lever
moves freely before proceeding. If it does not you may need to resize the hole(s) going through the choke
tower or use a 0.316" drill bit to make sure the hole is the proper size.

7. Insert the choke rod through the hole on the end of the bracket on the choke shaft. Secure the rod with the
1/2" cotter pin (Fig. 7).
8. Use the two T15 Torx® head screws to secure the choke flap to the choke shaft (Fig. 8). The flap has
instructions stamped on its upper side. Make sure you can read the instructions and that the arrow points
towards the choke rod. NOTE: It is extremely important that the choke flap is centered so it moves freely
and does not bind. You may need to remove the flap to deburr the edges if it binds and reinstall. Once the
choke flap is centered and moving freely, remove the Torx® head screws one at a time. Place a drop of
Loctite® 271 on them and reinstall. Wipe any excess Loctite® off the screw heads or shafts before
proceeding.
