<P>PROBLEM TO BE SOLVED: To provide a main jet for constructing a gasoline engine carburetor, withstanding corrosion by gasoline-water, eliminating deterioration caused by oxidation and degradation of gasoline itself, and maintaining initial performance for a long period of time. Ž<P>SOLUTION: The initial performance of a power source is maintained for a long period of time and air pollution is relaxed using stainless steel as material for the main jet metering main fuel in the carburetor supplying a gasoline engine with air fuel mixture. The process of working stainless steel which is material hard to be cut from row material is omitted in manufacturing the same through additional working of a stainless steel bolt on the market. Consequently, the main jet can be manufactured at low cost. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
