Thermoquad help - primary overfueled, boiling over on shutdown

Let me ask you does it do this when warmed up only ? In other words does it do it when its cold ? Because I had a simular problem on my 63 and my buddies 65. They would want to flood at times when hot. I went over everything in the carb but I noticed it always did it when warmed up on hot days. Never did it cold or warming up. The cheap pump gas fuel was boiling and causing the cars to flood and stall. Had to hold the pedal on the floor to get them stsrted. After and hr or so they ran fine. They added more ethanol to the pump gas fuel and I even had a guy from California tell me its becoming a problem in California also. Ron
 
As far as I know, yes. It's about impossible to avoid E10 around where I live though. I haven't had a similar problem with my AVS though.
