7. Insert the new bushing through the new choke
lever from the outside, and start the bushing in
the outer shaft bore. Position the choke lever so
the protruding boss on the carburetor housing is
between the two stops formed in the choke lever.
See Figure 5-30.
Figure 5-32. Choke Shaft and Spring Details.
10. Slide the choke shaft and spring into the
carburetor. Pivot (preload) the shaft 3/4 turn
counterclockwise with the inner leg of the spring
against the formed stop within the choke lever as
originally assembled. See Figures 5-29 and 5-33.
The outer leg of the spring must still be behind
the formed stop of the choke shaft.

8. Turn the old bushing upside down and use it as a
driver to carefully press or tap the new bushing
into the carburetor body until it bottoms. Check
that the choke lever pivots freely without
restriction or binding. See Figure 5-31.
Figure 5-31. Installing Bushing.
9. Install the new return spring onto the new choke
shaft, so the outboard leg of the spring is behind
the formed stop on the end of the choke shaft. See
Figure 5-32.
NOTE
: Make sure it stays in this location
during the following step.

Components.
11. Place a drop of Loctite
®
on the threads of each
new screw. Position and install the new choke
plate to the flat side of the choke shaft. Start the
two screws. Close the choke and check the plate
alignment within the carburetor throat, then
tighten the screws securely.
Do not
overtighten.
See Figure 5-34.
