Abstract: An accelerator for a carburetor that is linked to a throttle valve and allows a piston-type accelerator pump to be operated in a simple configuration that dispenses with a link mechanism and does not greatly enlarge the carburetor. The lower surface of a throttle valve lever 10 is provided with a cam 33 that has a circular shape centered about a throttle valve stem 8 and is configured such that the cam surface 33A thereof faces a carburetor main body 1. An accelerator pump 25 is placed parallel to the throttle valve stem 8 and the upper end of a piston rod 28 thereof is brought into contact with the cam surface 33A. The cam 33 pushes the piston rod 28 down as the throttle valve lever 10 swings in the opening direction of the throttle valve, and the acceleration fuel in the pump chamber 29 is delivered and supplied to the suction channel 2.

Abstract: The present invention provides a carburetor that can be adapted to a variety of engines with different positional relationships between the location for feeding the air/fuel mixture and the location for feeding scavenging air. The carburetor a carburetor main body (22) with an air intake passage (24) forming a portion of the air/fuel mixture passage (23) and is provided with an air passage (33) that forms a portion of an air channel (32) for scavenging air. The air passage (33) is positioned parallel to an air intake passage (24), and the front end thereof is positioned further to the base end side than to the engine-side front end face of the carburetor main body (22), enhancing the degree of freedom for placing the conduit pipe (34) for connecting the air passage (33) to the scavenging air feed port (9). Also, the throttle valve (26) and the air valve (35) are butterfly valves with mutually parallel valve stems, and the interlocking mechanism thereof has a simple configuration.
