Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello. Thank you for choosing Just Answer. My name is***** will be happy to assist you.
Toby, did you check the fuel filter inside your fuel tank?
Also, there is an inlet screen inside your carburetor, that may be partially clogged.
No problem. I would check the the screen, when you have a chance.
when you say running flat out, are you referring to your engine bogging down?
Your engine is running wide open, although your trigger is not in wide open position?
Now I understand you. Does your engine idle as it should?
The question above is a troubleshooting question.
I am wondering if you have an air leak, possibly between your carburetor, and your intake?
Or, if your throttle shaft is not fully closing after you release your trigger?
Yes, an air leak can cause an engine to automatically rev up. Another possibility. Make sure your throttle cable is on top of the plastic piece that your cable rides on, and is not under the plastic piece.
Yes, a new gasket between your carburetor and your intake.
You are very welcome! If the new gasket does not resolve our problem, I will be willing to continue working with you.
