3. Observe the reading from advance scale as
shown on figure 4.
4. Compare the reading with manufacturer's
specifications.
ADJUSTING TIMING TO SPECIFICATIONS
1. Loosen distributor holddown locking bolt
located at base of distributor enough so that
distributor may be rotated back and forth. Do
not overloosen or remove bolt but leave tight
enough to prevent distributor from turning by
itself.
2. Start and run engine.
3. Direct timing light flash at timing marks and
slowly rotate distributor right and left until
timing marks are aligned with pointer. See
figure 6. Stop engine.
4. Tighten distributor holddown bolt using care
not to change position of distributor.
5. Start engine and recheck timing.
NOTE: In some cases the ignition spark may jump to the
engine block or baffle. This may occur on those engines
such as late model Ford 8-cylinders where the timing
light adaptor spring is too close to engine metal parts.
In such cases, trace the wire from the spark plug to the
distributor cap. Disconnect the wire at the cap and
install the adaptor spring as shown in figure 5.

TESTING CENTRIFUGAL ADVANCE
With the timing light still connected and with
the vacuum line disconnected:
1. Speed the engine up slowly and watch the
timing mark.
2. The timing mark should remain stationary
until the engine reaches the manufacturer's
specified speed.
The timing mark should then move steadily and
without jerking. (See figure 6.)
3. If the mark does not move, or if it moves
erratically, the centrifugal (automatic) advance
should be serviced as necessary.
4. To check the maximum advance, it is necessary
to mark the harmonic balancer with the maximum
degree per manufacturer's specifications and
follow manufacturer's procedures.
