ring (132). Discard retaining ring.

Remove the governor cover (152) and cover gasket (151) from the assembly.

Once the cover is removed, ensure that gasket residue is completely

removed from the housing surface and no residue enters the inside of the

governor. Discard the cover gasket.

to fit in the holes by engaging first one side, and then the other

side. Make sure the tangs of the spring clip fully engage both the

feedback lever (105) and the speed-setting nut (115)

(Figure 3. item 20) to the side of the case (127) in the pre-existing holes. This

is the side that has the threaded breather hole (see photo).

spring coils, and through the other set of

lever bracket and mounting guide holes.
