ABSTRACT:
An automotive type carburetor has a choke plate or valve that falls by gravity or is moved by airflow from a closed engine cranking position to a variable number of cold engine running partially closed positions as a function of the differential force between a bimetallic coiled spring and a modulating spring, the positions being independent of engine intake manifold vacuum.
