ABSTRACT:
A variable venturi type carburetor includes a suction chamber, a suction piston moveable into and out of the chamber, a metering needle attached to the head portion of the suction piston, the needle being faced by a metering jet. The carburetor also includes a throttle valve. The head portion confronts the venturi section at the upstream side of the throttle valve. The head portion is obliquely cut or shaped at one side, which faces the throttle valve, and desirably is so positioned relative to the throttle valve that at least a portion of the throttle valve pivots during opening movement within space vacated by the obliquely cut or shaped piston portion as the piston moves in an opening direction.
