Slant 6 troubleshoot help!

I know this might be a silly question but it does have points and condenser setup right? My 71 valiant had a pertronix ignitor setup when I bought it and I was having problems just like yours for as long as I owned the car until I figured out my problem.

In several other posts I've made, I talked about tracking down a problem I had with bad idle and wicked (dangerous) stalling bogs when cold. I was fighting it for months, and I went through just about the entire ignition before I figured it out. One of the magnets had fallen out of the magnetic ring of my pertronix ignitor and I had no spark on the number 5 cylinder. I found it stuck to the bottom of the dizzy and I glued it back in and replaced the tape. Now the thing runs like new.

I went through plugs, plug wires, vacuum leaks, choke and pulloff, heat riser, carb rebuild, bigger jet, new float, air filter, valve adjustment, fuel filter and hoses, alternator, fuel tank sending unit, coil, cap and rotor, more cap and rotor, and all the wiring leading up to the coil. I bought an extra spark plug and put it on one of the wires and checked the color of the spark even. Eventually what I did was hook a timing light to each plug wire one after another and saw if there was any spark while the motor was running which eventually lead me to the number 5 cylinder misfire. The stupid pertronix rubbed the tape off one magnet because whoever installed it didn't adjust the plate the black module sits on properly.
