Abstract
The invention discloses a carburetor percolation prevention system which utilizes an electrically controlled fuel drain valve disposed in a fuel drain passage between the carburetor float chamber and the fuel tank. The electrical fuel drain valve is opened only when the engine condition sensor and the temperature sensor indicate that both the ignition switch is de-energized and the temperature near the float chamber exceeds a predetermined level.
