No, it's way simpler than that. You just have the spark plugs wires shifted
around on the distributor cap. For example, if you shift each plug wire one
nipple clockwise, you could rotate the distribute 90 degrees
counterclockwise, with the same timing. Play with this until it is in a
convenient position for fine adjustments.
