d. When the governor range of action is properly adjusted, allow the engine to run at governed seed, no load, and check for surging. If surging is

noted, turn in the surge adjusting screw (1) just far enough to eliminate the surging.

e. The surge adjustment can also be made by using the tachometer. With the engine running at governed speed, no load, turn in the surge

adjusting screw (1) until the engine speed increases 10 to 20 rpm and tighten the lock nut. If the carburetor and linkage are properly adjusted,

surge will disappear

f. If the governor cannot operate the throttle lever on the carburetor through the full operator range, it will be necessary to adjust the length of the

throttle rod (5) by loosening the nut (6) and adjusting the position of the ball joint (7).

g. When the governor adjustment is completed, tighten the speed adjusting lockscrew (2) to lock the cam in position. Make sure all locking nuts

are tightened.

If the governor cannot be adjusted, replace it.

(1) Disconnect the ball joint on governor to carburetor control rod from the lever on the governor.
