Abstract

PURPOSE: To obtain the mixed gas leaner than the air-fuel ration on the established base with the carburetor by arranging two pieces of exhaust pipes which allows the atmospheric pressure chamber communicating with suction system to communicate with the bypass port arranged on the wall directly above the main nozzle and the throttle valve in the carburetor.
