Crank the engine by hand until the breaker arm fiber block of points "D" is on the highest
point of the cam. Loosen screws "E" one-half turn and adjust points "D" to exactly .020" by
turning the eccentric screw "F." Tighten screws "E" and recheck opening to be sure it is exactly
.020".
Synchronize Breaker Points
Remove the spark plug from number one cylinder and
hold a finger over the plug hole. Crank the engine by hand
until a rush of air is felt. Continue to turn engine slowly
until the D. C. 1 and 8 mark is exactly in line with the
pointer on the inspection hole as shown at "A."
Loosen clamp screw "B" and turn distributor clockwise
to the full limit permitted by the slot in the clamping plate
"C." Turn the distributor slowly counterclockwise until
the points "D" have just begun to open. Care must be
taken to determine this position accurately. Tighten lock
screw "B."
Turn the engine slowly with the hand crank until the D.
C. 3 and 6 mark is exactly in line with the pointer on the inspection hole. This should require
only one-quarter (90°) turn of the crank.
Loosen screws "G" one-half turn and turn breaker point support plate clockwise to the extreme
limits of the screw holes. Turn breaker point support plate counterclockwise until the points "H"
just begin to open. This point must be determined accurately. Tighten screws "G."
The illustration shows the rotor arm in the proper position for firing on number one cylinder.
The cable to number one spark plug should be in the cap socket directly above the rotor point.
The spark plug cables should be in the cap in the order 1-6-2-5-8-3-7-4, following in a clockwise
direction.
Spark Plugs
When setting the gap of the spark plugs, make all adjustments by moving the side wire. Do
not bend center wire as this may break the porcelain.
To clean the carbon from the porcelain, fill the lower part of the plug with alcohol, liquid metal
polish or equal parts of ammonia and water, and allow it to stand for a few seconds. Take a piece
of wire covered with one thickness of cloth and rub the carbon from the insulator, wiping
thoroughly dry before replacing the plug in the engine.
Spark plugs should be changed every 10,000 miles for better engine performance. New spark
plugs give quicker starting, increased power, smooth running and a saving in gasoline.
