Over the winter, I removed, rebuilt and re-installed the 351C in my Pantera. All things considered, it all turned out pretty well. That said, I have a couple of nagging problems. The most irritating is about every third or fourth time I shut the engine down, I get a revolution or two of run-on. It is intermittent and brief but it is definitely there. I am speculating about the cause and cure and need help. Is it possibly a timing issue? Too much advance at idle?? Fuel issue? Spark plug heat range issue. All of the above have been suggested. Anyone have any thoughts or solutions?
Thanks,
Joel
