"I have watched hot steamy gasoline boil and dribble into my hot intake many times."


I had the same problem with my 750 Holley on my 318, the bowl's were getting so hot you couldn't touch them up by the carb base. The whole problem was solved with a 1/2" plywood spacer under the carb, the bowl's are almost cool to the touch now and it doesn't sound like coffee brewing in the carb anymore, i do still get a little smoke out of the primaries but no fuel dripping above the throttle plates.
