Abstract

The present invention is to prevent mixing of fresh air and an air-fuel mixture when a throttle valve is fully opened and increase a delivery ratio. A main nozzle () is surrounded by a tunnel-like air flow guiding member (). The air flow guiding member () is opened at its front and back sides. A whole amount of fuel discharged via a main nozzle () is sent to a downstream side by an air flow created by the air flow guiding member (). When a throttle valve () and a choke valve () are both in a fully-opened state, fresh air flows into an air-fuel mixture passage () through a gap between these valves ().
