Checking Timing (Static)

Timing should be set to 10° BTDC (1970 models) or 7° BTDC (1972-73). Adjustment should be made with engine not running, so that other malfunctions (early vacuum advance or incorrect centrifugal advance) can be detected later. To adjust static ignition timing, proceed as follows:

1. Rotate crankshaft until it reaches correct timing mark (see specifications above) as shown by observing fixed timing pointer and timing mark on crankshaft pulley. Remove distributor cap and connect a 12 volt bulb between primary terminal of distributor and a good ground. When ignition is switched on, bulb will light when contact points are open.
2. Loosen distributor clamp screw and rotate distributor counterclockwise until contact points are closed. Turn ignition on and apply light finger pressure to rotor in a clockwise direction. Turn distributor clockwise until blub just lights. Tighten distributor clamp screws.
3. Check setting by turning crankshaft one revolution clockwise until bulb again lights. Correct timing mark on crankshaft pulley must be opposite fixed pointer on timing case.
