Dan, what I might try is to drive the car, let it cool a bit (maybe an hour), drain the carb (through one of the lower attachment bolts on each bowl), and pull the carb off to see if there is any fuel inside the intake.
My fuel was definitely percolating at first - I could see it through the sight glasses on the carb. I added a 1/4" phenolic spacer and insulated all the fuel lines under the hood. It solved the problem. Here is my post with the parts I used:
Solution for fuel percolation/heat soak
Now, if I take the air cleaner off after a drive I can see some of the fuel vapor coming off the carb, and the level in the float bowls drops a bit over the next few hours and then stabilizes. But I don't smell any fuel.
