PURPOSE:To recirculate the fuel in a fuel sump through the positive pressure in the crank case into a fuel tank when restarting an engine, by providing a fuel sump in a return path communicating between the float chamber of carburetor and the fuel tank while connecting the pressure lead path communicating with crank case to the fuel sump. CONSTITUTION:When starting an engine, a fuel cock 6 is opened to feed the fuel in a fuel tank 4 into a float chamber 3a. When stopping the engine, the fuel cock 6 is closed while a drain cock 8 is opened to transfer the fuel in the float chamber 3a into the fuel sump 9. When re-starting the engine, the fuel cock 6 is opened while the drain cock 8 is closed. The positive pressure in the crank case 2 will function through a pressure lead path 10 into the fuel sump 9 to push out the fuel and recirculate through a return tube 7 into the fuel tank 4. |
