Ah, the curve's the thing!

My old Pertronix had two curves. There was the one around idle, and the one that went from around 2200 on up.

In between, there was so much 'scatter' that you couldn't see the timing marks when you pointed a timing light at the pulley. And that's just where the, uh, 'fuzziness' in the throttle response was. I don't think there was anything wrong with the Pertronix module - just with the crappy, mechanical advance mechanism underneath. Another stunning example of Chinese repops that look like the original but don't work half as well.

I also have a theory about how dizzies curved for basic VW engines don't work so well on Type 1's like the ones most of us drive, with hotter cams, but that's for another day.

 

exactly why the Wilhoit distributor works so well on Whitecloud, the advance is early and precise, the Bosch cast-iron distributors were/are well made options though expensive
