Too‐Rich Mixture

We listed possible causes of the problem too‐rich mixture:

1. High fuel pressure
2. Oil in cylinders
3. Carburetor float valve seating improperly
4. Float leaking air
5. Jet gaskets of improper thickness or out of shape
6. Float level too high (these troubles would be responsible for the carburetor flooding and a rich mixture, particularly at low speeds)
