Usually an engine running WFO will be either an air leak between the carb and the engine. Or a failure of the governor . Two most common govenor failures, broken connection spring or loose connection at the govenor shaft.

How does the governor work on a small engine?

To control engine speed, a mechanical governor uses gears and flyweights inside the crankcase to detect changes in the load and adjusts the throttle accordingly. This closes the throttle, limiting the air-fuel released into the engine. When the engine load increases, the crankshaft spins more slowly.

What is minimum governor speed?

Minimum speed: The Minimum speed is nothing but the speeds at the minimum radius of rotation of the balls without tending to move either way is called as minimum speed. 8. Governor effort: The mean force working on the sleeve for a given change of speed is termed as the governor effort. 9.

How do you adjust the governor on a golf cart?

If you find this rod, then your governor can be easily adjusted by accessing the cart’s inner workings. Simply adjust the cable coming from this metal protrusion, turning the nut counterclockwise to make the cable longer, effectively adjusting the cart’s governance to increase the overall speed.

It is observed that when load is applied on the engine, the speed tends to decrease which is known as rpm drop also, to compensate the speed, governor is used in all stationary or mobile engines which run on either single speed or variable speeds.
