no discourse from me. im trying to figure out the best way to do it. Im thinking that the width of the terminal in the cap and the width of the contact on the rotor are such that when everything is properly phased, the rotor contact will sweep the width of the cap terminal throughout the advance.

i dont run vacuum advance. only mechanical. If my theory of sweep is correct and my belief that the mech advance changes the position of the rotor wrt to the cap terminal, then I can mess with mine.

im just trying to visualize everything in my head right now and its not working too well for me. once I get a distributor in my hands, im sure I'll figure out what i need. right now, im researching
