b. Inspect.

(1)

Check to see that all parts are in place and free of dirt and obstruction.

(2)

Clean and lubricate the steel ball joints of the governor linkage, using a drop of light oil or graphite. The

linkage must be able to move freely through its entire range.

(3)

Check the governor arm, linkage, throttle shaft, and lever for a binding condition or excessive slack and wear

at connecting points. A binding condition at any point will cause the governor to act slowly and regulation will be poor.

Excessive looseness will cause a hunting condition and regulation will be erratic.

(4)

Install the air cleaner (see para 4-62).

c. Adjust. (see figure 4-35).

If it is necessary to make adjustments while the engine is running, use extreme caution when close to

hot exhausts, moving parts, etc.

NOTE

On a new replacement engine the governor is set at the factory to allow a nominal engine speed of

2400 rpm at no load operation. Proper adjustment is one of the most important factors in maintaining

desired engine power and speed.
