Thanks for the link vdriver.
Chris, I popped the cap right after it wouldn't start hot, for any pressure, and there didn't seem to be any.
adding vent lines seems like a lot of work than I want to tackle right now on the car.
I am going to start with a phenolic spacer once I figure out which carb/ intake set up I have at what spacer I need.
I hear that, no reason to fix a problem you easily ruled out. I'm with you on the spacer at this point, as a solution to fuel bowl boil (as was pointed out early on).
