Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is John.
What kind of help are you looking for? I will see if I can assist you.
Can you provide the model and serial number from the machine so that I can better assist you?
It sounds like the governor system is stuck on the engine which would explain the overspeed problem and with it overspeeding it would create a lot higher hertz and voltage output. I would check the governor linkages and make sure that they are all working freely. It could be that your pushing too much LP through your pressure regulator as well, may need to be readjusted.
Yes the governor shaft should rotate about a 1/4 of a turn if not a little more. This could be your problem.
The gas bbq regulator may not work in this application. The gas is regulated on a bbq using the control valves on the unit, you really need an adjustable regulator on this application otherwise you have no other way to regulated the amount of lp going into the engine.
