I have to agree with Rick and Eljaro regarding the need to check the pump bypass or drain jet. When I first installed 48 IDA's on my car, I also had a post-shutdown flooding problem. The 48 IDA Webers were originally delivered with a zero (or closed) pump drain jet and several minutes after engine shutdown, I could hear and see fuel dripping out of the accelerator pump nozzle into the throat of the carbs. This occurred when the temperature of the carb body exceeded 140 F several minutes after engine shutdown while using available pump gas. I first tried adding an insulator below each carb but finally eliminated the problem by going to a 35 pump drain jet.
