Dynamic Timing

EQUIPMENT REQUIRED
- Calibrated Tachometer
- Stroboscopic lamp

ADJUST
1. It is essential that following procedures are adhered to. Inaccurate timing can lead to serious engine damage and additionally create failure to comply with emission regulations. If timing is being checked in vehicle, air conditioning compressor must be disengaged.
2. On initial engine build, or if distributor has been disturbed for any reason, ignition timing must be set statically to 6° BTDC.

NOTE: This approximate setting is made only to ensure that engine may be started.

CAUTION: On no account must engine be started before this operation is carried out.

3. Connect timing light and tachometer to engine following manufacturer's instructions.
4. Disconnect vacuum hose from distributor.
5. Start engine. With no load, and without exceeding 3,000 rpm, run engine until normal operating temperature is reached (Thermostat open). Check that engine idles within tolerance specified.
6. Idle speed for timing purposes must not exceed 750 rpm. This speed should be achieved by removing a breather hose, NOT by adjusting idle setting screws.
7. With the distributor clamping bolt loosened, turn the distributor until the timing is at 5° BTDC ± 1°.
8. Retighten the distributor clamping bolt securely, and recheck timing in the event that retightening has disturbed the distributor position.

WARNING: Personal injury may result if an attempt is made to adjust distributor while engine is running.

9. Refit vacuum hose.
10. Disconnect stroboscopic timing lamp and tachometer from engine.
