PURPOSE:To shorten the length of a starting fuel passage and low speed fuel passage either as well as to suck sub-fuels in an easy manner even at the weak suction pressure of an engine, by installing a sub-fuel chamber beneath the suction passage of a carburetor body. CONSTITUTION:A sub-fuel chamber 4 holding sub-fuels including gasoline, etc., is solidly set up with a carburetor body 1 beneath a suction passage while a low speed fuel passage 5 and a starting fuel passage 7 are installed. Moreover, a main fuel chamber 9 is set up separately from the carburetor body 1, but attached to the body 1 at the side of the suction passage. In addition, a main nozzle 11 and a main fuel passage 10 interconnecting the nozzle 11 with the main fuel chamber 9 are installed as a main fuel system. |
