Heating

15.1

Carburetor heating

Current is supplied via wires to the
heating element installed between
filter base and carburetor.
The heating element is controlled
via the temperature regulator on the
carburetor.
The heating element must also be
checked if running problems occur
when the cold engine is idling or
running at part load, particularly at
sub-zero temperatures.
Idling problems with a hot engine
may also indicate a fault in the
heating element.
