I'm having a problem with getting my distributor to full advance as described in Marcos' 1999 paper.
Specifically, I'm not getting the full range. The paper states the arm should swing the full distance of the slot in the distributor body. At full retard the arm just barely touches the body. And with the advance lever full advance, there is 1/4 inch still to travel in the body slot. Net result, I don't think I'm getting the benefit of full spark advance. I have a 28/29 column, but it's mounted to Randy's F100 box. My thought is rotating the column will only move the area of the slot traveled. It won't increase the travel distance. Am I missing something?
