A downdraft type carburetor induction passage has essentially a constant cross-sectional area with a rounded edge air inlet, the rounded edge cooperating with a rotatable member having its peripheral surface in the form of an inverted semi-venturi so as to form an inverted venturi whose area varies as a function of the rotation of the member to provide high fuel metering signals at low air flows and high air flow potential. |
