PROBLEM TO BE SOLVED: To reduce labor hours and a cost in manufacture, by easily and precisely forming throw ports with various bore diameters, various numbers, or various shapes which are required for a synthetic resin carburetor for a general purpose engine. SOLUTION: The carburetor for a general purpose engine has a synthetic resin body 1, and has a low speed system. In the carburetor, a throw port chamber piece 10A having an idle port, the throw port 10b, and a throw port chamber 10a is formed separately from the body 1. The throw port chamber piece is fit in a mounting hole 11a of a mounting part penetrating an intake passage 2 from an outer face of the body 1. Even if the synthetic resin of the body 1 contains glass fibers, the idle port, and particularly, the throw port 10b can be easily, correctly, and accurately formed. COPYRIGHT: (C)2006,JPO&NCIPI |
