Yet another Pertronix thread, I know. I put a Ignitor 1 in my 66, 352, this weekend. Easy install, but cylinders 2&3 are not firing. I tried setting the "airgap" a few times with no success. I put my old points back in and all is well. I actually did this a couple of times with the same results. I have a new Crane 30k coil if that matters. I left all the rest of the wiring alone. Any idea? Bad unit? I even installed a new cap and rotor just to make sure. Thanks!
There are a few tricks...first off, put one of those rubber hose washers (the type that goes in the hose female end to prevent leaks) inside the black Pertronix ring that goes onto the top of the distrib, this raises the height for better match up to the sensor. Second, the gap tool they give you may be a hair too much, play with it a bit. One other thing, the black ring that goes onto the distrib. has 8 magnets in it, spaced out...check to see the polarity of the magnets, you may have a bad ring...Pertronix sees this from time to time, and replace them...takes a while to get it though...at least for me. Also, be sure your coil has a good amount of
juice, the Pertonix FlameThrower is good and so is the MSD II.
Hope that helps...

Thanks for the tips. I thought the gap seemed large as well. I'll try all the tricks again tomorrow. The coil is a dandy new one, working great. I knew somebody had some secrets out there.
Directions actually suggest running 12v staright from the battery if unit malfunctions to eliminate the low voltage possibility as a test. Made zero difference, so power to the unit is not the issue, but thanks.
I narrowed the air gap a bit and that helped. Only 1 cylinder not firing. I tried moving the magnet piece around and could kill off any 1 cylinder at a time. Mine is an all black sealed magnet, so magnets cannot be repositioned. I then tried the washer trick, ( actually I have some hi-temp silicone o-rings) and voila! Truck fire right up and smooth as silk. Timing was even dead on.
Another question, is it a good idea to go ahead and change the plug gap then? 045 is correct? Thanks.
i think you should increase the plug gap since you're using a hotter coil- not specifically b/c you're using a Pertronix. more voltage=more ability to jump the plug gap.
