Saab 96 - Ignition Timing

* Ignition Timing
Since the timing of the three cylin
ders in relation to each other is
fixed by the shape of the cam, it
is sufficient to check the timing of
one cylinder only. Engine and dis
tributor are indexed with cylinder
2 as determinant for the timing,
which is carried out as follows:
1. With the distributor cap re
moved and the breaker
points adjusted, turn the
crankshaft until the index
on the crankshaft pulley
coincides with the crankcase
index underneath the distri
butor, as shown in fig. 26.
The piston in cylinder 2 is
now at its top dead centre.
2. The index of the rotor
should now coincide with
the index of the distributor
body. This index is located
on the rear side of the body
and to the left of the guide
lug which also serves as a
support for one of the clamp
springs. See fig. 28.
3. Switch on ignition and by
using a test lamp for indi
cation, turn the crankshaft
until the breaker points
close. Make sure that the
advance regulator weights
are retracted by turning the
rotor anticlockwise. When
the setting is correct the
