Ignition Timing: Adjustments

1. Start engine and allow to reach normal operating temperature.

Tachometer Hook-up:

2. Connect a tachometer test probe to terminal IG of the check connector, (located in the engine compartment), or the negative terminal of the ignition coil.
NOTE: Never let the tachometer lead touch ground as this could cause damage to the igniter and/or coil. Be sure to check that your tachometer is compatible with this ignition system. Consult the operating manual for your instrument.

Installing Jumper Wire:

3. Using a service wire, connect terminals TE1 (or T) and E1 of the check connector.
4. Connect the timing light power source terminal to terminal 30 of the starter, and and the test probe to the #1 high-tension lead (light blue).

Ignition Timing Mark (5):

5. Using the timing light, verify that the mark on the pulley is aligned with the 5 mark on the timing cover.

Ignition Timing: 5° BTDC at idle

6. If not as specified, loosen distributor hold-down bolt and rotate distributor housing until marks align.
7. Tighten the distributor bolt and recheck the ignition timing.
8. Remove service wire from check connector.

Ignition Timing Mark (12):

9. Check idle advance timing with service wire removed.

Ignition Timing: 12° BTDC at idle

10. Check idle speed and adjust if necessary.
11. Disconnect tachometer and timing light from engine.
