the old mounting gaskets for the air cleaner and
carburetor.
2. Clean the areas around the choke shaft and the
self-relieving choke mechanism thoroughly.
3. Remove and discard the plastic cap from the end
of the choke lever/shaft assembly.
4. Note the position of the spring legs and the choke
plate for correct reassembly later. See Figure

plate to the choke shaft. Pull the shaft out of the
carburetor body and discard the removed parts.
Figure 5-35. Choke Details.
5. Use a screw extractor (easy out) and remove the
original choke shaft bushing with the old choke
lever from the carburetor housing. Save the
bushing to use as a driver for installing the new
bushing. Discard the old lever.
6. Clean the I.D. of both choke shaft bores as
required.
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
that the protruding boss on the carburetor
housing is between the two stops formed in the
choke lever. See Figure 5-36.

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 5-37.
