Ignition Timing: Adjustments
IGNITION TIMING INSPECTION AND ADJUSTMENT1. WARM UP ENGINE TO WARM UP TO NORMAL OPERATING TEMPERATURE.
2. CONNECT TACHOMETER AND TIMING LIGHT TO ENGINE.
- Connect the tester probe of a tachometer to terminal IG(-) of the DLC1.
NOTICE:
^ Never allow the tachometer terminal to touch ground as it could result in damage to the igniter and/or ignition coil.
^ As some tachometers are not compatible with this ignition system, we recommend that you confirm the compatibility of your unit before use.
3. CHECK AND ADJUST IGNITION TIMING.
- Using a jumper wire (or SST 09843-18020), connect terminals TE1 and E1 of the DLC1.
- After engine rpm is kept at 1,000-1,300 rpm for 5 seconds, check that it returns to idle speed.
- Using a timing light, check the ignition timing.
Ignition timing @ idle: 10° BTDC
(With transmission in neutral position)
- Loosen the bolt (California) or 2 bolts (Federal), and adjust by turning the distributor.
- Tighten the bolt (California) or 2 bolts (Federal), and recheck the ignition timing.
Torque: 19 Nm (195 kg.cm, 14 ft.lb)
