Float level refers to the height of the fuel in the carburetor’s float bowl. It is important to check the float level periodically to ensure that the carburetor is functioning properly. If the float level is too high, the carburetor will flood and cause the engine to run rich. If the float level is too low, the carburetor will not be able to supply enough fuel to the engine and the engine will run lean.
Checking the float level is a relatively simple procedure. First, remove the air cleaner from the carburetor. Then, use a screwdriver to carefully remove the float bowl from the carburetor. The float level should be set so that the fuel level is about 1/4 inch below the top of the float bowl. Once you have set the float level, reinstall the float bowl and the air cleaner.
