Abstract
An electric choke assembly includes a heater to heat a coiled bimetallic spring which opens a choke valve. The heater comprises a double ring electroded thermistor for the purpose of generating two different heating rates which are controlled by a bimetallic thermostat blade located in the same chamber of the assembly as the thermistor.
