1. Remove the carburetor from the engine. Discard
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 top
of the choke lever/shaft assembly.
4. Note the position of the spring legs and the choke
plate for correct reassembly later. See Figure
5-28. Remove the two screws attaching the choke
plate to the choke shaft. Pull the shaft out of the
carburetor body and discard the removed parts.
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 5-29.
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 5-30.
9. Install the new return spring onto the new choke
shaft, so the upper leg of the spring is between
the two formed stops on the end of the choke
shaft. See Figure 5-31. Note: Make sure it stays in
this location during the following step.
