help...carb issues

['70_402]

my truck has been running fine lately..untill the last few day when it almost wants to die when i slow down and stop.. but runs fine when going down the road and at full load..(wide open) but i noticed today at lunch that my vacume guage wasn't working and while i was trying to figure that out i heard a "drip..ssssss...drip..ssssss" and i took off the cleaner lid and there was gas dripping out of one of the squirters in the two primary bowls...so there was nothing i could do about it so i put the cleaner back on and then i noticed that there was another leak..dripping on to the manifold from the carb (see pic below) what could be causing this... and now it acts like it is flooded when i go to start it in the afternoons...could this issue be related to the vacume guage? it is running directly from the manifold..not the carb..if not what could these be??

thanks in advance...
