I just went through a round of trouble shooting ignition problems with a Pertronix ignition. I bought the third generation and it didn't work out well for me. Pertronix is sending me a second generation unit.
What I did learn though was that the easiest way to set timing with the solid state ignition is with an advance timing light. At 500rpm, before the centrifugal advance comes on, point the timing light at your marker, and dial in the advance you want. Dead simple.
