PURPOSE:To facilitate the carburetion of fuel with a simple device by providing a carburetion chamber for reserving fuel of specified volume at all times and providing plural perforated pipes which are immersed in the reserved fuel inside this carburetion chamber and communicated with an air cleaner. CONSTITUTION:A carburetion chamber 4, which is supplied, by a fuel pump 3, with fuel from inside a fuel tank 1 and in which the fuel is always reserved up to the specified level by the operation of a float valve 6, is provided and plural perforated pipes 7 provided with many small holes 7a are arranged in parallel with each other in the reserve part 4a of this carburetion chamber 4. Each perforated pipe 7 is connected with an air cleaner 9 through an air valve 8. Further, a mixing chamber 4b provided above the reserve part 4a in the carburetion chamber 4 is connected to a suction air manifold 11 through a throttle valve 10 and each end part of this suction air manifold 11 is connected to the suction port of each cylinder 12. And when the air is sucked in by the suction air negative pressure of an engine, the air is discharged from each small hole 7a foamingly and made contact with the fuel so as to promote the carburetion of the fuel.
