Checking Timing

Timing should be 7° BTDC. Adjustment must be made by loosening and rotating distributor. 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 7° BTDC 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 as contact points open.
  2. Loosen distributor clamp 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 body clockwise until bulb just lights. Tighten distributor clamp.
