Abstract
An amount of air taken into an air leading type two-stroke engine is increased to enhance an engine output, and gas emission characteristic deterioration caused by blow-back is inhibited. An inhibition memberis disposed between a choke valvein a full open position and a throttle valvein a full open position. The inhibition memberincludes, for example, a mesh member like a metal mesh. Mixed fuel containing oil is supplied to the air-fuel mixture channel. Numerous pores of the inhibition member(mesh member) are occluded by a membrane of oil components of the mixed fuel. Consequently, entry of a blow-back flow of an air-fuel mixture from the air-fuel mixture channelinto the air channelthrough the numerous pores of the flow inhibition member(mesh member) can be inhibited.
