Governor Sensitivity Adjustment
Governor sensitivity is adjusted by repositioning the governor spring in the holes in the governor lever. If speed
surging occurs with a change in load, the governor is set too sensitive. If a big drop in speed occurs when a
normal load is applied, the governor should be set for greater sensitivity.
The desired high speed seing (RPM) will determine the governor spring position in the governor lever and the
throle lever, as well as the spring used. See Figure 5-27 and 5-28.
