A variable Venturi condition responsive carburetor wherein a control ring, movable in response to engine operating conditions regulates the amount of air that is mixed with incoming fuel as it passes through metering tubes to provide for total air fuel mixing prior to its being introduced into the combustion chambers of an internal combustion engine. The control ring also regulates the amount of fuel supplied through the metering stem, provides a means for providing automatic compensation for fuel mix changes necessary due to changes in atmospheric pressure such as will occur during altitude changes and regulates flow through a demand fuel circuit. An arrangement of fixed and movable Venturi elements is used to vary the fuel flow through the carburetor in response to the throttle linkage manipulation.
