ABSTRACT:
A carburetor has a choke control device that acts in connection with a thermoplastic control to permit the carburetor choke valve to be closed during starting but provides a controlled gradual opening of the choke valve after starting. The device includes a self-cleaning purge feature for continual cleaning of the device. A simple one way choke valve device and precision by-pass give exact control of the choke opening. A back pressure valve is provided to prevent back fire damage to the unit.
