Dual point distributor question

I can't believe this "alternating fire" crap -- WTH is the advantage compared to a single-point?? My factory dual point distributor uses the pair of points to increase dwell (they are adjusted separately, but the dwell is overlapping on the same cylinder). If one pair burns out, it will run off the other, well enough to get you home. But on this "4 lobe" Mallory, you'd be running on 4 cylinders.... that just seems idiotic. I agree, I wouldn't even mess with it, if that's how it works.

But back to the original question -- if you don't understand how to set a point gap, you really have no business messing with a dual point system. Do yourself a favor and go electronic -- it works better anyway, and is way less hassle. The only reason to go dual points is old-school bragging rights, or concours scoring.
