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.

A vapor return primer for priming and regulating pressure in a carburetor is disclosed. The vapor return primer includes a housing having an inlet and an outlet. The inlet is coupled with the high pressure side of the carburetor. The outlet is coupled with a fuel tank. A resilient flexible membrane is coupled with the housing for moving fluid through the inlet and outlet to prime the carburetor. A pressure relief mechanism is coupled with the housing to provide one-way flow from the housing through the outlet to the fuel tank during priming. Also, the pressure refief mechanism regulates the carburetor pressure when the internal combustion engine is in a continuous running mode.
