Abstract
A carburetor achieves better emission characteristics while improving a combustion state by increasing a delivery ratio of a stratified scavenging engine and reducing intake resistance. No dividing wall is provided between a throttle valveand a choke valve, and a gapbetween the valvesandis opened. Intake air in both of an upper region and a lower region of the choke valveflows into an air-fuel mixture passagein a lower region of the fully-open throttle valve. A main nozzleis arranged so as to be inclined toward the throttle valve
