Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello thank you for choosing Just Answer. My name is***** will be happy to assist you. Your engine is revving up and down due to your carburetor starving for fuel.
Check to see if you are getting a good, steady flow of fuel from your fuel tank to your carburetor. Also, check your fuel shut off solenoid, to see if it works properly.
Your fuel solenoid should click each time you turn your ignition switch on and off. If you are getting a good flow of fuel to your carburetor, and your fuel solenoid is ok, then you will need to give your carburetor a really good cleaning.
Larry, we can continue from here. Thanks!
You have not been billed. You will not be billed until you are satisfied. My suggestions above are part of a troubleshooting process. Sometimes there is no way around a good carburetor cleaning. Your satisfaction is important to me.
Surging / rpms up and down, indicates a fuel restriction in your carburetor, in most cases.
Thanks for letting me know. I am glad you got the problem resolved. I do hope all continues to go well for you. If you like, I can forward your question to customer service for a refund.
