Abstract
A carburetor for minimizing the variation in the ratio of fuel contained in the fuel-air mixture due to fuel evaporation within the float chamber. The carburetor has an air passage providing communication between the float chamber and the air intake pipe at a location upstream of the throttle valve. A further air passage provides communication between the float chamber and the air intake pipe at a location disposed downstream of the throttle valve, which further air passage contains a throttle therein for controlling the flow therethrough.
