the Parts Manual for the engine being serviced to
ensure the correct repair kits are ordered.
Reassembly
Choke Shaft Installation (Non-Self-Relieving)
1. Install the choke return spring to the choke shaft.
2. Insert the choke shaft with return spring into the
carburetor body.
3. Rotate the choke lever approximately 1/2 turn
counterclockwise . Make sure the choke return
spring hooks on the carburetor body.
4. Position the choke plate as marked during
disassembly. Insert the choke plate into the slot
in the choke shaft. Make sure the choke shaft is
locked between the tabs on the choke plate. If the
choke plate was attached with screws, loosely
attach the plate to the shaft. Close the choke and
center the choke plate in the bore. Tighten, but do
not over-tighten the screws. Check that the choke
moves freely and that the plate does not bind in
the bore.
Choke Shaft Installation (Self-Relieving)
WARNING: Prevent Eye Injury!
Suitable eye protection (safety glasses, goggles,
or face shield) should be worn for any procedure
involving the use of compressed air, punches,
hammers, chisels, drills, or grinding tools.
1. Before installing kit parts, thoroughly clean the
carburetor body with compressed air.
2. Install the new bushing through the new lever and
align the slot in the bottom of the lever over the
lever stop pin. To ensure the proper alignment of
the upper bushing and the lower shaft hole use a
3/16 diameter drill blank to align the bushing as it
is pressed into the casting.
3. Install choke shaft and spring assembly with the
lower spring tang installed in the second notch
from the right. See Figure 5-11.
Figure 5-11. Choke Lever with Cap Removed.
4. Loosely attach the choke plate to the choke
shaft using the two screws provided in the choke
repair kit. Apply Loctite
® No. 609 to the threads of
the choke plate retaining screws. Secure these
screws ONLY after the choke plate is properly
aligned in the choke bore. To align choke plate,
insert a .010 in. shim between the top right edge
of the choke plate and bore. See Figure 5-12.
Then while pushing down on the top of the choke
shaft, tighten screws securely.
Figure 5-12. Measuring Clearance.
5. Check choke shaft and choke plate for freedom
of movement by performing the following:
a. Using the choke lever, close the choke plate.
The choke lever and choke plate should
move in unison.
b. While holding the choke lever in the closed
position, push on the long side of the choke
plate. The choke plate should open and
spring closed freely.
c. While holding the choke lever in the wide
open position, the choke plate should be
against the wide open choke plate stop pin.
6. Install new dust cover by pushing it down until it
snaps into place.
7. After the carburetor is reinstalled on the engine,
recheck choke system for freedom of movement
by moving the wire link in the direction to close
the choke and releasing it. The link should move
freely in both directions.
