69 Dart Hard to Start When Hot, Starts Fine Cold. Vapor Lock?

Is it points or electronic ignition???

If it's electronic, check the reluctor gap in the distributor... It should be .007" with brass feeler gauge... If the gap is too big, it will cause hard starting when warm...

Brand new Pertronix ignition. That being said, it did the same thing when the points were in there. I will double check the gap anyway.
