Figure 11:

1. Install the choke shim that was included in the emission kit as described in Figures 10, 11, 12, 13, and 14.

Shown in Figure 10 is a basic outline view of the choke mechanism.

Note:
The area between the choke adjustment screw and the plunger is behind the choke linkage and is hidden from view.

Figure 12:

2. Using the Fast Idle Release Driver special tool, insert the tool between the thermo wax element housing and the choke linkage (Figure 12).

Figure 13:

3. Spread the choke linkages to create a gap between the choke adjustment screw and the plunger of the thermo wax element. Make sure not to interfere with the throttle lever or other linkages (Figure 13).

Figure 14:

4. With the linkages spread, install the cap portion of the choke shim onto the threaded end of the choke adjustment screw. The cap portion of the shim should be inserted between the plunger and the choke adjustment screw (Figure 14).

5. Remove the fast idle release driver. Carefully twist the handle of choke shim and allow the handle to break off the cap portion.
