tension terminal, and that the O-ring is in its proper place. Make sure the leads are not closed to the secondary terminal,
or do not extend beyond the coil so that the leads are pinched between the cover and the base assembly.
c. Coat all base plugs and pipe connectors with Permatex No. 2 and install them.
d. Connect an air hose to one of the ventilating air holes in the base and plug the other holes. Apply 6 pounds of air
pressure and submerge the unit in water. If bubbles appear at any point except around the drive shaft, correct the cause
of the leak.
e. Time the distributor according to paragraph 98.
f. Install the distributor as instructed in paragraph 97b.
Section X. GOVERNOR
205. Description
A small heavy-duty governor mounted on the crankcase top cover controls the engine speed through the gasoline
carburetor throttle. Incorrect governor adjustments, carburetor settings, or binding governor linkage may cause a surging
of engine speed known as "hunting." Should this condition exist, check the governor levers and rods for binding. Refer to
paragraph 110. The slightest drag on the linkage will cause the governor to over travel as it opens and closes the
carburetor butterfly valves to maintain a constant speed. Lubricate the control rods frequently to prevent binding.
206. Governor Disassembly
a. Remove the governor (par. 110a).
b. Unhook the governor spring (9). Unscrew the top hex nut (34) and remove the level (36). Remove the four oval
fillister head screws (13) and lockwashers (12) and remove the governor mechanism with the gasket (10). Remove the
four cap screws (28) with lockwashers (27) and lift off the speed change bracket (33) with its attached parts. The
