Why does my onan generator surge

Place the transmission in Neutral or Park. Start the engine and let it warm up. Check the condition of each plug. Reinstall the plugs and start the engine. Locate the idle speed and idle mixture screws on the carburetor, if so equipped. A carburetor that's incorrectly adjusted is a common cause of poor engine idling that results in hunting and surging. Fortunately, most lawnmowers have two screws that allow you to adjust the carburetor yourself.

Then slowly adjust the screws tighter or looser in turn until the mower runs and idles smoothly. If they are flashing, such as clock radios, there is a chance the power strip experienced a surge. Test any equipment plugged into the power strip. Smell the area around the power strip. Locate the strip's reset button. The best way to test an electrical outlet for power surges is with a surge protector.

Obtain a surge protector with an internal breaker. Plug the surge protector into the outlet. Check the surge protector periodically to see if the circuit breaker has tripped. Why is my Onan generator surging?
