Timing Curve

Understood. I just now saw the arrow you drew on the MSD chart, which is going back to my original springs. But if both are lengthened to get both stages in earlier that should be a safer set up.
Snowing here today, looks like Saturday is the next reasonable day to play with this. I’ll have to find something else to obsess over till then!! :lol:


If you really want to go berserk, try changing the weight and/or shape of the advance weights.

Working on a Pertronix distributor, and to get the curve I think it should have, I had to not only change the weights, but modify them.

What a giant PITA.
