I was hoping someone on here could tell me how long I reasonably could expect a Pertronix ignitor ignition to last. I installed one on my 56 Victoria 292 about 12 years and about 50,000 miles ago. It has been trouble free. I started it yesterday morning and let it warm up in place only to discover that it had died minutes after I walked away. It started again ok and ran until I had to stop for a light where I had to do a brake stand to keep it running. About a mile later when I arrived at my destination it stalled as I parked it. It would not fire to start again and I suspected it had jumped time as the vacuum wipers would jump a bit as I released the key. I called AAA and tried it one more time while I was waiting. It started and ran ok on the way home and ran great today in the driveway. I am afraid to drive it anywhere. The holley carb seems to be okay and I suspect the petronix. I hope someone on here knows how long these units last. George
