1. Disconnect the negative battery cable.
2. Remove the distributor cap.
3. Locate the points. They are located on the side of the distributor.
4. Use a feeler gauge to measure the gap between the points. The gap should be 0.016 inches.
5. If the gap is incorrect, use a screwdriver to adjust it.
6. Replace the distributor cap.
7. Reconnect the negative battery cable.
8. Start the engine and check the timing.
Note: The point gap can also be adjusted with the engine running. With the engine running, disconnect the vacuum advance hose. Slowly move the point set until the RPM increases. Turn the point set slightly back until the RPM starts to drop, then return it a slight amount in the opposite direction. That should set your best spark. Reconnect the vacuum advance after adjustments.
