Cam Angle (On Vehicle)

With engine running at idle speed, lift window on side of distributor cap and insert a 1/8" Allen wrench into adjusting screw. Turn screw clockwise to increase cam angle and counterclockwise to decrease it. Use dwell meter to set cam angle to specifications.

If a dwell meter is not available proceed as follows: Turn adjusting screw clockwise until engine begins to misfire, then turn adjusting screw counterclockwise 1/2 turn. This will give approximate dwell angle required.
