Just installed Pertronix in the stock vacuum advance distributor along with new cap, rotor, blue coil, and wires in my '73 1.7. Problem is that it is running rough, especially around 4500 rpm and higher. Does the timing stay the same (27 degrees BTDC @ 3500) with the pertronix or does it change? Any help would be great! Thanks. (IMG:style_emoticons/default/mad.gif)

It's been my experience that fitting the Pertronix often shifts the timing some. They don't necessarily get the sensor it exactly the same place as the points. On some cars, it shifts by enough that you can't even start the car. Pull out the timing light and reset it.

the car ran ok before the tune up, I also replaced the ignition switch as well because I was losing all power while driving. I tried to get the timing the best I could, I know it needs to be perfected some, it's better with two people, than trying to do it alone.
