Abstract
An automatic choke assembly or starting aid is coupled with a small internal combustion engine. The choke assembly is responsive to a pressure differential in the internal combustion engine which causes movement of a mechanism to control the amount of combustion air entering into the internal combustion engine. The mechanism provides sufficient combustion air during start-up and during continuous running condition of the internal combustion engine.
