625 AVS leakage

I think it is leaking out of the bowl. I never had this problem with the new 650 AVS I put on my Duster. I could let it set a week and it would fire right up. I have to use starting fluid whenever I try and start it after a couple of days. I noticed gas running out of the carb and evaporating. I do think there is a problem with it. It is a stock A-Body so I really do not want to hide an electric pump on it. I can if I need to but I do not want to, OK?
