13. Carburetor Heating
System
Current is supplied via wires to the
heating element installed between
the baffle plate and carburetor.
Carburetor heating is controlled by
a thermostatic switch on the heating
element.
The carburetor heating system
should be checked if running
problems occur when the cold
engine is idling or running at part
load, particularly at temperatures
below freezing.
Idling problems with a hot engine
are also an indication of a fault in the

carburetor heating system.
