Saab 96 - Spark Plugs

points begin to open at 10°, or if a dial gauge is used, 0.7 mm
(.028 in.) before T.D.C. If a dial gauge is not available, the distance
between the pulley index and the crankcase index, fig. 26, may be
measured. The distance measured on the pulley periphery corre
sponding to 10° is 12—13 mm (i/2 in.).
If adjustment of the timing is required, proceed as follows:
a. Turn the crankshaft until the piston of cylinder 2 is 10°
before T.D.C. (See item 3 above). Note, that the indexes on
the rotor and distributor body should coincide, see fig. 28.
Loosen screw 8, fig. 28, and turn the distributor until the
breaker points open. Make certain that the advance regulator
weights are retracted.
When the correct setting is obtained, tighten the distributor
lock screw.
Check the correctness of the timing by turning the crankshaft
a few full turns.
4. Clean the distributor cap, inside as well as outside, with a dry
and clean cloth, and check that all contact faces are clean and
undamaged. Also check that the center carbon terminal 5 slides
freely in its holder. Clamp on distributor cap so that the lug on
the spring attachment fits in the corresponding notch. Check
that the ignition cables are correctly inserted and make good
contact. If required, the distributor shaft should be lubricated
through the nipple at the front of the distributor body and at the
felt in the shaft under the rotor, which must be removed.

Important
All high tension insulators must be kept clean and dry.
The following parts should be cleaned every 6,000 km
(4,000
miles): ignition coil bakelite cap, distributor cap
(inside and outside), ignition cables and spark plug
insulators.
Spark Plugs
The spark plugs should be cleaned after approx. 6,000 km (4,000
miles) driving. At the same time, check with a feeler gauge that the
spark gap is 0.7 mm (.028 in.) If adjustment is required it must be
done with the side electrode since the insulator may crack if the
