Figure 103 reChecking flywheel timing with
timing light
An alternative method without timing light, is
as follows :
1. Remove ¢~1 Spark Plug -- put your thumb
over the spark plug hole and crank engine by
hand until air is exhausting.

Without Timing Light
(Emergency Method)
4. Start engine and run at idle speed, 400 RPM
or lower, so the automatic advance of the distributor
is completely retarded. THIS IS VERY IM-
PORTANT TO OBTAIN CORRECT TIMING.
5. Direct timing light on the crankshaft pulley
or on the flywheel through opening in bell housing
and note timing marks as light flashes.
6. Timing is normally at "D.C." unless specified
otherwise on your engine specification sheet.
7. To advance timing, turn distributor body
clockwise. To retard timing, turn distributor body
cou nter-clockwise.
8. When timing is correct, tighten distributor
clamp screw securely. Then recheck timing again
with light.
9. This operation is best performed in shaded
area, so timing light is visible.
2. Set piston on top-dead-center by slowly cranking
until "DC" mark on flywheel (or crank~
shaft pulley) will line up with the pointer in
bell housing (or gear cover).
Note: Some special applications may be timed
several degrees before top dead center (BTDC).

3. Loosen the distributor clamp bolt and rotate
the distributor body until the contact points just
Start to Open.
This may be more accurately checked by means
of a test lamp connected between the distributor
primary lead and the negative terminal of the battery
-- when the points are closed the light will be
ON and as soon as the points break the light will
go OFF.
