ABSTRACT:
A carburetor adapted to change a rate of fuel flow and an air bleeding characteristic so as to optimize the engine operation irrespective of change in fuel, for example, from gasoline to alcohol or change in altitude. The carburetor includes a main nozzle opening to an intake passage, a fixed support cylinder having a peripheral wall formed therethrough with a plurality of apertures, the peripheral wall being surrounded by an annular chamber communicating with the intake passage upstream of the main nozzle, and an air bleed pipe rotatably fitted in the fixed support cylinder and communicating with the main nozzle and a float chamber. The air bleed pipe has a peripheral wall formed therethrough with a plurality of groups of air bleed ports of different air-bleeding characteristics so that when the pipe is rotated relative to the fixed support cylinder, one group of the air bleed ports are placed into communication with the apertures in the fixed support cylinder so as to change the air bleeding characteristic. A cylindrical change-over valve is operatively connected with the air bleed pipe for integral rotation therewith and adapted to be operated from the outside for changing the degree of communication between the air bleed pipe and the float chamber.
