Abstract

PURPOSE: To feed a proper amount of fuel from a second main nozzle by installing a third main jet being variably controlled in parallel with a second main jet to be normally opened to a lower part of the second main nozzle of a variable choke carburetor.
CONSTITUTION: In this carburetor, there are provided with a second main jet 8 being normally opened to the lower part of a second main nozzle 7 in order to meter fuel to be fed to this second main nozzle 7 and a third main jet 9 in parallel with this second main jet. The third main jet 9 is controlled by interlocking with a throttle valve 1. At more than the specified value of opening of the throttle valve 1 where the opening of an air control valve 2 becomes larger, a needle valve 11 installed in the lower part of an accelerating piston 10 operating in linkage with the throttle valve 1 is pressed down and opened. Consequently, the fuel passes through the needle valve 11 from a fuel passage 13 by way of a float chamber 12 and is metered by the third main jet 13, then it is compounded with the fuel metered by the second main jet 8.
