fuel cock


fuel cock
A tap which can allow or restrict the flow of gasoline from the gas tank to the carburetor. An essential item on a motorcycle with gravity feed (i.e., no fuel pump) because if the fuel cock is left on after the engine is shut down, there is the possibility that gasoline could leak past the needle and seat in the carburetor so that the overflow in the float bowl will make its way into the cylinder and wash the walls and dilute the oil
