Ok, so I finally decided to convert to the Pertronix Ignitor II system today.

Right when i opened the box, the tape around the magnet wheel was loose, and one of the small magnets fell on the pavement. Super hard to find, but I found it, and put it back in, and taped it up smooth. So I did the install, and also put in the Flamethrower II coil.

This is on my '66 200cid coupe, by the way. It ran really smooth with a points system, but as soon as I put in the Pertronix system, its running really rough. I thought maybe it was a matter of loose connections, so i checked everything and tightened all the connections. Still rough, so I thought maybe I needed to adjust the timing for the new system. It didn't seem to make a difference, as i kept trying to set it at the 12 deg mark and it seemed impossible.

I'm not quite sure what the problem is, has anyone else run into this issue?

 

UPDATE:
i went out and reinstalled all the Pertronix parts and reseated all the connections, and hit it with the timing light. If the timing marks continued all around, it would probably be on 28 degrees. Ridiculous.

Edged it off and it seems to be smooth at high rpms. in reverse and idling its a little rougher. Any timing tips?

 

As long as you have 12 volts to unit it should fly,,,,bought a pertronix II about 2 years ago or so ,,,shot craps on me,,pined it down after replacing everything else,,( multipul witnenesses to the whole circus) sent unit back for warranty repair,,got a note back and they said the unit was ok,, and heres the good part,,THEY FIXED IT ANYWAY?,,,anyway the NEW unit wasn't/didn't run right and has now taken another dive, I have a backup unit it it now ,,will buy a Pertonix I to get by and then buy an MSD unit....somehow lip service doesn't make for good warranty service,,especially now that the original warranty is long gone and it looks like to me and my friends they sent me a unit to just get past the warranty issue,,,good luck with them ..I've had enough of quality parts ,,to just eat it again and again

 

I had some problems when I installed mine, similar to yours. How do you have the wiring run? My problem was because I did not have a full 12V run to it. Pull off a boot from a spark plug and stick a screwdriver into it. Hold the boot end and hold it so that the screwdriver is close to some engine metal.... make sure u get a nice blue spark arcing from the screwdriver to the engine metal. If not, you will probably need to bypass the pink resistor wire that steps down the voltage.

 

Mine did the same thing - threw the timing off a LOT. ~ 45 degrees off. Crraaazzyy...I just played around with it for about an hour and a half till it sounded perfect.

 

how much of an arc should i get to the metal, inches-wise? also how should i bypass the resistor wire, simply snip it?

 

Hold it close, maybe 1/16 of an inch. If you have a strong spark, it will probably jump further than that. You bypass the pink resistor wire by either cutting it out completely or bypassing it. Either way, you will need to run a new wire from the + side of the coil and solder it to a 12V source such as your ignition switch.

 

If i install a 20gauge jumper wire on each end of the pink resistor wire, will that cancel out the resistor and allow me to leave the original wiring?

the only reason i ask is that should i ever get stranded on some backroad and have to rely on the points/condenser/coil in my trunk, i'll need that resistor wire.

Thanks for the help!
