Abstract
A carburetor has a vacuum operated diaphragm type choke control device that acts in connection with a thermostatic control to permit the carburetor choke valve to be closed during starting but provides a controlled gradual opening of the choke valve after starting. An adjustable stop member permits adjustment of the opening by limiting the extent of movement of the diaphragm. The device includes purge feature for continual self-cleaning of the device. A one-way check valve device and precision by-pass means give exact control of the choke opening.
