Choke Shaft Installation
1. Install the detent spring and ball into the carbure-
tor body.
NOTE:
If the detent ball does not drop through
the tapped air cleaner base screw hole by
its own weight, do not force it. Forcing
the ball could permanently lodge it in the
hole.
Install the ball through the choke shaft
bore instead.
2. Compress the detent ball and spring. Insert the
choke lever/shaft assembly into carburetor body
with the cutout portion of shaft facing the air clean-
er mounting surface (refer to Figure 6B-11).
Make
sure the choke lever is on the correct side of car-
buretor body.

3. Install the choke plate to choke shaft. Make sure
the plate is positioned properly in bore as marked
and noted during disassembly. (The numbers
stamped on plate should face the air cleaner
mounting surface and be upright.) Apply Loctite®
#609 to threads of 2 plate retaining screws. Install
the screws so they are slightly loose.
4, Operate the choke lever; check for binding be-
tween the choke plate and carburetor bore. Ad-
just plate as necessary; then torque screws to
8/12 in. Ib.

Carburetor Reassembly
1. If the welch plugs have been removed for сіеаг-
ing, new welch plugs must be installed. Use tool
No. KO1017 and the following procedure to install
the welch plugs.
a. Position the carburetor body securely with the
welch plug cavities to the top.
b. Place a new welch plug into the cavity with
the raised portion up. Use the end of the tool

c. After welch plugs are installed, seal the ex-
posed surface with Glyptal™ (or an equivalent
sealant). Allow the sealant to dry.
NOTE: If a commercial sealant is not available,
fingemail polish can be used.
2. Install the main fuel jet and torque to 12/16 in. Ib.
3. Install fuel inlet needle/clip assembly, attach clip
to the adjusting tab on float as shown in Figure
6B-13, slowly lower float into position in seat.
4. Set Float Level: Invert the carburetor so the float
tab rests on the fuel inlet needle. The exposed
surface of float should be parallel with the bowl
gasket surface of the carburetor body (exposed,
free end of float .690"/.720" from bowl gasket sur-
face). Refer to Figure 6B-14.
