valve (kit model no 08712).
Refer to Figure 61 for this procedure.
1. Wash the lift valve in solvent and dry thoroughly
2. Carefully mount the lift valve in a vise so that the valve mounting surfaces
are against the jaws of the vise and the cap of the lift valve is facing upward.
3. Remove the 2 hex cap plugs from the side of the valve body. Remove the
spring, check ball, and cam pin from behind each hex cap plug.
