Abstract
An automatic choke for a small internal combustion engine uses an air vane responsive to an air flow created by a radial fan to position the choke valve during engine starting. A return spring or gravity may be used to reset the automatic choke after the engine has been stopped. The automatic choke includes a thermally-responsive device that keeps the choke at least partially open during hot restarts of the engine.
