Automatic Choke Carburetor
The automatic choke consists of a vacuum choke
break and a thermostat. The Intake manifold
vacuum activates the vacuum choke break which
partially opens the choke plate, to prevent over
choking while the engine is being started. A vacuum
limiter, located in the vacuum line, regulates
vacuum to the vacuum choke break.
The thermostat contains a Positive Temperature
Coefficient heater (P.T.C.) and a bi-metal spring
which opens the choke plate gradually as the
engine is running. When the keyswitch is turned
“ON,” the battery current activates the P.T.C. heater
which heats the bi-metal spring.
The P.T.C. Heater is a heat sensitive
semiconductor porcelain. As the P.T.C. heater
temperature rises, resistance increases, which
regulates battery current to the heater and
maintains the proper temperature for the bi-metal
spring.
