Adjustment
Ignition Timing
Should it be necessary to reset the
ignition timing, loosen the distributor
adjusting plate lock screw "B." If the
adjustment is being made because of
sluggish performance, turn the distrib-
utor counterclockwise one division of
the scale on the locking plate. Tighten
screw "B" and try the performance of
the car on the road. A slight spark
knock should be heard when the car is
being accelerated on a level road in
high gear at ten to twenty-five miles an
hour with the throttle wide open. This
gives the best performance and fuel
economy.
If a spark knock is not heard, turn the distributor one division counterclock-
wise as before and test again. If the knock is too loud, turn the distributor
clockwise one-half division at a time to reduce the knock until it can just be
heard by the driver.
Should the distributor require any other adjustments, the car should be taken
to an authorized Hudson or Electric Auto-Lite Service Station. The following
instructions are given for use in case of an emergency, but should not be
attempted by the owner unless absolutely necessary. The results obtained
from these adjustments depend entirely on the accuracy with which they are
performed.
Adjust Distributor Points
Breaker points should be clean, flat and spaced .020" when at their
maximum opening.
Remove distributor cap and inspect points and clean if necessary. A special
breaker point file or stone should be used. Place file or stone between points
and move straight up and down, dressing both points at the same time.
Crank engine by hand until the breaker arm fiber block of points "H" is on
the highest point of the cam, giving the points their maximum opening. Adjust
the opening to exactly .020" by loosening the lock nut and turning the
adjusting screw on which the stationary point is mounted. Tighten lock nut
.
