4. Remove the fuel line from the carburetor. There may be a clamp holding the fuel line in place. Use pliers to loosen the clamp and pull the fuel line off.
5. If the carburetor has a fuel filter, it is highly recommended to replace the old one with a new one.

Tips:
- Be careful not to damage the float when cleaning the carburetor. The float is a small, metal or plastic component located in the carburetor bowl. The float controls the fuel level in the carburetor.
- If the carburetor is badly damaged or worn, it may need to be replaced. A new carburetor can be purchased from a lawn mower dealer or online.
