IGNITION
TIMIN
G
Particular attention must be paid to correct ignition timing.
In
many cases
poor performance, high fuel consumption
and even damage to the engine
can be the result of incorrect ignition setting.
T
he ignition must not be ad-
vanced arbitrarily not even when using premium grade
fuels.
Before setting the ignition timing the
breaker
contact point gap must be
checked. With the breaker arm fully open the clearance should be 0.4 mm
(.016"
).
T
he initial spark advance must be set
to
10°
before top
dead
centre.
The
ignition timing must only be set with the engine cold or when it is slight-
ly warm.
CLEANING
CONTACT
POINTS
The
contact points must be smooth and make even contact with each other.
Dirty contacts should be cleaned and,
if
pitted, smoothed with a contact
file.
Whilst
doing this, the contact points are pressed lightly
together. After-
wards the ignition distributor
should
be blown
out carefully with air. If the
points are
badly
burnt they must be replaced.
