With it becoming worse after it gets warm, metal and gasket material expands somewhat. Isuspect a leak at, near or within the booster/valve if equipped.
My guess to, a vac leak somewhere.

Does anybody have ideas? Or, is this post so long you didn't get to the end and just gave up? lol
Thanks, Dave
My friend Pat had put a Pertronics on his '67 400. He was lucky to be carrying the point set he took out, for it broke down coming back from the lake. Start with the simple stuff and work your way up.
