Ok lets get to basics, since you are running points, how did you set them. I would check them with a dwell meter to be sure they are in 28-32 * range to start with. Point when setup will work fine, they are not as trouble free as electronics but they were use for many years.
My gut feeling is your accelerator pump arm is possibly not adjusted correctly or the squirter is to small. There are several articles on this adjustment. If it is adjusted too loose it could cause the lean pop and can potentially take out the power valve. There should be no play at idle and at WOT you should be able to move it about .015 more, this will avoid bending parts. A blown PV can cause sooty plugs.
Also have you checked the Pertronix instructions to see if it will run on the resistor wire of if it requires full battery voltage. If it requires full voltage and you are running it through the old resistor wire this will cause all sorts of issues.
