Install Choke Shaft Bushings
1 . Install screws in the tapped holes that enter
the choke shaft bores until the screws bottom
lightly. Refer to Figure 6-10.

choke shaft bushings with Loctite from the kit.
Carefully press the bushings into the carbure-
tor body using a smooth-jawed vise. Stop
pressing when bushings bottom against
screws.
Models K91 - K181 (112" Carb.); Make sure the
bushing is pressed below the surface of the large
choke shaft boss until the bushing bottoms against
screw.
3. Allow Loctite to "set" for 5 to 1 0 minutes,
then remove screws.
