Hi Jerry, thank you for the question. You need to take the carburetor off, take it apart, and clean the screen that has the buildup on it. Try cleaning it with carburetor cleaner. Get yourself some carburetor cleaner and gently spray that out on the debris. Clean all that debris using a small piece of wire and kind of scrape that out of there in the screen, and then spray a little bit more carburetor cleaner to get any of the other gunk off, and then put the carburetor back on. We hope this information is useful!
