I know this is a F**D question but, I haven't found a fix on their forum yet.
I have a 67 pickup, 240 ci six. It starts right up when cold but when I drive it for a few miles and try to restart the engine, it turns over really, really slowwwwwww. Then all of a sudden it will turn over normally. I have changed the starter, solenoid and wires from solenoid to the starter. Being winter and its cold outside, I would think of heat soak to the starter could be ruled out. Normally I can let the truck sit for 15-20 minutes and I can start it right up.
It started to do this shortly after I changed the points to the pertronix type. Could this have anything to do with it?

Thanks,

Mike

PS I do have a 69 Chevelle

Are there any ground wires going from the frame to the engine, there is sometimes one from the frame to the center of the three bolts that hold the starter in, check it out.

Is your distributor advance moving freely?

I'll check tonight on both suggestions and let you know.
Thanks for the hints, I sure appreciate the time and effort that everyone gives.

Heh, my flag is gone, I guess it is time to renew.

Thanks,

Mike
