amccomb. yes it's a problem with these carbs. I learned that I can hot-start by treating it like it is flooded (which it is). when you go to start (hot), don't pump the accelerator just hold it down. I also found, at least on mine, that I only have to hold it 1/2 to 2/3 open (rather than all the way to the floor like you'd normally do with a flooded carb).
that doesn't cure the problem of course, you'll want some type of insulated spacer. there are several types, including ones made from wood which is an excellent insulator. Edelbrock makes this (which I bought 'cause I don't want/need a spacer):

I actually haven't put it on yet since the method described works and I don't drive the truck much. I just haven't gotten around to it
