Fuel Compensation
The foregoing operations give dead center timing. This, however, due to variations
in fuel characteristics (octane rating), is only approximately correct. 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 7 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 (D), Figure
35, and turn the distributor counter-clockwise one graduation of the clamping plate
(E), 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 more than 3/4" ahead of the upper dead center mark on the flywheel.
Starting Motor
The starting motor, Figure
37, located at the left rear corner of
the engine, is operated by a solenoid
switch (A) mounted on the top of the
starting motor. Control of the starter is
through a remote control switch located on
the instrument panel, Figure 32.
The drive to the engine is through the
Bendix drive located at the rear of the
starter which is brought into en-
gagement by the rotation of the starting
motor.
It is necessary to turn on the ignition
switch to engage the starter, and, in
addition, on cars equipped with Electric Hand it is necessary to depress the clutch pedal.
The starter may be engaged manually by unscrewing the cap (B) on the
solenoid switch and depressing the plunger.
Generator
The generator, Figure 38, mounted at the left front corner of the engine, is of the
fully ventilated type which permits high output. It will be noted from the illustration
that the cool air is drawn through the generator from the rear end by means of a
suction fan located at the front of the generator.
The maximum generator output is reached at approximately thirty-five miles per
hour, and virtually constant high output is maintained at high car speeds.
The maximum output on Series 81 models equipped with radio and all
Series 82 models is controlled by the third brush and an external Voltage Regulator,
which is mounted on the left side of the dash, under the hood. The maximum
generator charging rate with hot generator, that is, after the engine has been
