Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello. Thank you for choosing Just Answer. I will be happy to assist you. Do you have some carburetor cleaner in a can?
I can help you locate it, What brand is your engine? What are the model numbers for your engine?
Thanks for these numbers. Click on the link below. Your carburetor is behind your air cleaner housing.
Glad you found it. The purpose of the carburetor cleaner, is to see if your engine will either start up and continue to run, or if your engine will start up and run briefly, after you spray carburetor cleaner into your carburetor.
If your engine will only run briefly, afterwards, then I would check to make sure you are getting a steady flow of fuel to your carburetor. If so, then you will need to give your carburetor a really good cleaning.
The old gas has likely contaminated your carburetor, and clogged either your main jet, or the small fuel passages inside your carburetor.
I prefer using carburetor cleaner for this purpose, rather than starting fluid. The brand does not matter.
You are very welcome!
