Choke Control. The carburetor choke control knob is located
directly' above the hand throttle control knob (fig.
8).
The
purpose of this control is to dose (or partly close) the carbu-
retor choke valve. This restricts the air intake and produces
a richer fuel mixture for starting while at the same time open-
ing the throttle by means of a fast idle link on the carburetor
on all truck models except those equipped with an updraft
carburetor.
When the engine is' warm and the weather is warm,
it
should not be necessary to use the choke when starting the
engine. When it is necessary to use the choke for starting, it
should be pushed part way in as soon as the engine starts and
all the way in as
~,on
as the engine will run smoothly without
its use.
CAUTION: Excessive use of the choke will provide a fuel mix-
ture too rich to burn. Some of this unburned fuel
