To provide a variable venturi type carburetor capable of feedback control with a simplified structure.
The variable venturi type carburetor comprising a cylinder part 13 and a fuel guide hole 14 being disposed on a carburetor body 11, opposed each other across an intake air flowing passage 12, and a piston 16 to which a needle 17 is fixed being driven by a wire 18 to move inside the cylinder part 13 up and down and thus to vary a venture diameter of the intake air flowing passage 12. The carburetor body 11 is adapted to have a housing part 15 communicating with the cylinder part 13, and also to house a sliding operation type variable resister 21 inside the housing part 15. Locking an operation lever 21b of the variable resister 21 to a locking part 16a provided on an upper circumference wall of the piston 16 enables the variable resister 21 to directly detect a position of the piston 16.
