How should the governor be adjusted on a model 126332 OHV engine?

Adjusting the governor on a model 126332 OHV engine is critical for ensuring proper throttle response and engine speed control. The recommended method involves setting the engine to full throttle, which ensures that the governor operates within its designed parameters for managing speed under load conditions. By turning the adjustment arm counterclockwise while at full throttle, you're allowing the spring tension to properly position the governor in relation to the throttle linkage. This adjustment helps to achieve the desired maximum engine speed without over-revving, thus promoting optimal engine performance and longevity.

After making this adjustment, retightening the bolt is essential to secure the governor arm's position. This ensures that the adjustments made will not drift due to vibrations or engine operation. Proper adjustment prevents the engine from running too fast or too slow, which could lead to performance issues or even engine damage.

Other methods of adjustment, such as those involving idle settings or complete removal of the governor, do not provide the same level of precision and risk compromising engine safety and functionality. Maintaining the governor in its intended configuration is crucial for the engine's operation and for adhering to safety protocols.
