I have a recent problem that started a couple weeks ago. It was really brief the first couple times and was just a second or two. Engine doesnt diesel it runs just like the key is still on. Yesterday it was probably 5-6 seconds. Havent had any issues with the ignition switch doing everything else it is supposed to. Thinking something else may be feeding power back to the engine. Running a Pertronix set up. Any ideas?
Have you done any work on the car recently before this started?
Years ago I had this and the wire that feeds 12 volts to the coil from the starter solenoid while you are cranking was touching the positive cable connection on the solenoid. In essence, my car had hot wired itself.

No. I havent done anything to it. Wondering if some wiring has been compromised with vibration and what not. Think Ill change out the ignition switch first as it is easy and then will start following the wiring trail. Also not sure even if its consistent now which will make it frustrating. Put a mini starter in it a couple years ago.
I don't know much about Pertronix. Do they still use the stock coil? If so, when you shut it off what if you put a test light on the coil + to see if it has power?

Soooo sort of an interesting end to the story.
Going back a couple weeks I had done a couple hour road trip and the car couldnt have run better. Good power and it seemed to run on fumes. Seemed to use hardly any gas.
Then this. Went over to a friends place Monday and as I drove back it got sluggish. Backed into the driveway and it stalled. Looked under the hood and popped the air cleaner off. Tried to start it and out bubbles some gas. Pop off the carb and pulled it apart. Separated the float and it didnt feel right. Gave it a little shake and there was my answer. I could hear the ocean splashing in there. So spent $40 on a rebuild and float kit, put new plugs in as the old ones were carboned up some and it was back to a smooth running engine as I went about my errands today. Always nice when there is an obvious solution.
The part that fooled me the most at the beginning was it didnt seem to diesel when it ran those extra seconds when in reality it was. Combination of some hot carbon on the plugs and with lots of fuel in it, it didnt want to stop quite yet.
On a positive note I got a complete tune up for under $70 and was able to figure it out and do it myself. I love these old cars.
