Carburetor Boiling Issue

Had this problem about a month ago. Needle and seat stuck. Took carb apart and just blew it out. Car still acted funny. Think that I got a load E 15 or worse, I had just filled the car up. It seemed like something wasn't right and then the engine quit. Gas was boiling and dumping out the boosters. I used to haul gas, we called it a miss drop, but never told anyone.
