Assuming a distributor: Static timing is used to set the initial timing. Set the point gap to .020". Under the flywheel there is a hole that allows the viewing of the timing mark. Assure that the #1 cylinder is on compression TDC (cylinder toward radiator). Put a circuit test light on the distributor side terminal and a ground to assess the voltage there. Loosen the distributor at the flange. Turn on the ignition and rotate the distributor clockwise (looking from the rear) till the light goes out. Then turn it back CCW till the light just comes on (points Break). Tighten the clamp, and shut off the ignition. The engine is now timed pretty much as it is designed to be adjusted. A small amount of advance can be dialed in if the starter doesn't kick back, and no Spark Knock happens. DO not do this if the engine is hand cranked, it must be at TDC. If it is a mag, the mag should have its points set to .013". The mag should be turned in the same way the distributor is turned so the impulse coupling does not trip as the engine is rotated to TDC. This sets the impulse coupling to cocked position as the engine is set to TDC. Now rotate the mag CCW till the impulse clicks. Lock it down. and it is now set. There is no Centrifugal advance on the Mag, it goes to max advance when started. Jim
