hard hot starts?

If I drive around for a half hour or longer and get the car good and hot, then shut it off and go into 7/11 or something and come back out I have to hold the throttle open a bit and it takes a few seconds to start. It smells like gas when I shut it off too. Its an eddy 600 cfm. Could my floats be adjusted wrong? could it be something else? any ideas would be helpful.
