<VV> VirtualVairs Digest, Vol 81, Issue 106

[Eric S. Eberhard]

Pertronix 1 and Pertronix II are different animals.  Pertronix II 
adjusts the dwell real-time.  It can help compensate for a poor 
distributor and it does keep you from having to deal with the dwell 
-- both of those items could be causing your problem.

I use Petronix II coil and ignition with battery voltage at the coil 
(a little better than 12 volts generally).

Also use 8mm wires  and good plugs that won't foul.

Often the problem you describe is the distributor ... is it 
sloppy?  Old/new?  I had one car with a real bad one, and the 
Pertronix masked it for a long time and it ran OK.  With points it 
ran like your car. I finally got a Clarks rebuild and it made a large 
improvement.

Do NOT use a Pertronix II coil or high output coil on a Petronix 1 
ignition or it will die.  Use stock or Petronix 1 coil.  I am 
surprised the P1 instructions say not to use 12 volts, they used back 
when there was no P2 ... but people put hot coils in and burned them 
out.  I have never had a P2 fail or behave badly (despite the CORSA article).
