should be exactly .020". If adjustment of the gap is required, loosen lock nut
(H) and turn adjusting screw (J) until the proper gap is obtained. Tighten
lock nut (H) and re-check the gap.
Turn the distributor housing clockwise to the limit of the slot in the
clamping plate (K). Remove the central cable from the distributor cap and
place the bare end about %8 from the intake manifold. With the ignition
turned on, turn the distributor body counterclockwise slowly just until a
spark jumps from the high tension wire to the intake manifold. Tighten
clamp screw (F), replace central cable in distributor cap and clamp cap on
distributor.
The foregoing operations give dead center timing. This, however, due to
variations in fuel characteristics (octane rating), is only approximately cor-
rect. To get the correct setting the car should be driven until the engine has
reached its normal operating temperature. Allow the car to slow down to 8
miles per hour in high gear on a level, hard-surfaced road, then depress the
accelerator rapidly to its limit of travel. As the car accelerates from 10 to 15
miles per hour a slight spark knock should develop. If a knock is not heard,
loosen distributor clamp screw (F) and turn the distributor counterclockwise
one graduation of the clamping plate (K) and repeat the acceleration test.
Repeat this operation until the knock is heard. The higher the octane rating
of the gasoline being used the greater the advance required to get maximum
performance and fuel economy. However, the timing should not be set ahead
of the 3/4" advance mark.
Carburetor and Fuel System
The carburetor is of the down draft
type, incorporating Climatic Control
(self-controlled choke), automatic
heat control, and an accelerating
pump. The only manual control for
the operator is the accelerator pedal
controlling the throttle opening for
regulating the speed of the engine.
The choke valve, the mechanism for
which is contained in the insulated
housing (A), Figure 5, is fully closed
when the engine is cold at aver-age
air temperatures (75 ° Fahrenheit).
Hot air drawn off the exhaust mani-
fold through the stove (B) and tube
(C) enters the control housing, giving
accurate positioning of the choke for
all starting and operating conditions.
