Greetings Olds Fans, I installed a Pertronix ignitor kit in my ‘72 Cutlass about 4 years ago. Earlier this week I took the distributor cap off and found a thin, clear plastic ring had delaminated from the magnet ring. It was hanging down inside the distributor so I removed it. On my next test drive it was running and idling rough like it had a miss. I called Pertronix technical support and was told that the clear plastic ring on the bottom of the magnet ring will delaminate after 5-7 years. He explained that when this happens it act like it has a miss. I thought well, this is good information for anyone running their conversion kit.

 

From my experience with Pertronix, I would throw the unit in the garbage and put a good set of points and a condenser back in it. Pertonix left me on the side of the road more than once in the 54 I had and I limped home a couple times.

 

I'm an old man, I have owned many points eliminator kits. This one has been my car for many years, works flawlessly. This is the only one I would ever recommend, it is great.

Good info. I'm an HEI guy but I'm sure lots of Pertronix users out there will appreciate knowing about this if their engine develops a miss.
