To fix a carburetor that is running rich, you will need to clean the carburetor, inspect the float valve and needle valve, and adjust the air/fuel mixture screw.
Here are the steps on how to fix a carburetor that is running rich:
- Clean the carburetor. Remove the carburetor from the engine and disassemble it. Clean all of the parts with carburetor cleaner. Be sure to pay special attention to the jets, passages, and valves.
- Inspect the float valve and needle valve. The float valve is responsible for controlling the fuel level in the carburetor. The needle valve is responsible for shutting off the fuel flow when the fuel level reaches the correct level. If either of these valves is faulty, it can cause the carburetor to run rich.
