carb overheating?

I have a 84 c-10(STOCK) and am in TX with Tx summers usually about 100+ for a few months, pretty extreme conditions. I am using a rebuilt quadrajet and have tuned it and like where its at, but the fuel in the bowl seems to be heating up and over flowing. After driving for about 30 minutes and shutting off, if I go back to turn it on the engine is flooded. I can also see where fuel has pushed out up around the top of the carb. The float level is as low as the book recommends.
One issue is all the old stock emissions lines. I did not want to remove them even though they were not working and unplugged, everything was there and I wanted to keep it as stock as possible. Well , last night I could not leave it alone anymore , stock or not, it just wasnt helping and was hurting the issue. Having about 20 hoses across the front of the intake was block all air from flowing around the carb.
I have ordered a 1" phenolic spacer for the carb so that should help. I wanted to keep the truck as stock as possible(but thats seems impossible) but I think next will be to remove the steel intake and install a quality alumn. Its a daily driver and stock HP output.
Should I block off the heat cross over in the intake? Anything I am missing? So much for keeping her stock:rolleyes:

Before you do anything, I would check to see just where your fuels lines are coming to the carb.
You may have the line too close to the exhaust header or somewhere down the line it may be getting hot from something back farther.
I've seen guy wrap their lines with protective heat wrap and solve the problem you have.

I also found another issue thats helping to heat the carb. I replaced the thermostat with a lower degree one and splashed water on the intake. After the instal , I bolted everything back together and fired her up. Within 5 minutes the water boiled away around the base of the carb which seems to show that the heat cross over passages are not blocked in the intake. So a big help seems to be to block the passages to keep the heat from below the carb. In colder climates I believe you want the cross over open but in Texas I dont think it does me any good. I got the phenolic spacer installed and am diggin it!!!
