The carburetor might be cracked, or the carburetor float might be stuck open. Over time, the carburetor can develop cracks due to the vibration and heat of the engine. If the carburetor is cracked, it will leak fuel. Inspect the carburetor for cracks or corrosion. If the main body of the carburetor is cracked, you will most likely have to replace the carburetor. If the carburetor is not cracked or damaged, inspect the carburetor float to see if it is stuck open. If the float is stuck open, remove the carburetor and clean it thoroughly. If cleaning the carburetor is not effective, rebuild or replace the carburetor.
