ABSTRACT:
A variable stage type carburetor has a vane controller adapted to forcibly bias a vane to a smaller opening degree when a throttle valve has been opened nearly to the maximum opening degree and, accordingly, the venturi vacuum is small. Between a limiting lever connected to a diaphragm of the vane controller and an interlocking lever connected to the vane, provided is an interlocking spring for affording a relative movement between the vane and the throttle valve. The interlocking spring can be deflected with a reduced force when the throttle valve has been opened nearly to the maximum opening degree.
