Camaro Carb 4bbl 305

(IMG:http://www.frrax.com/rrforum/style_emoticons/default/banghead.gif)
Let me start off by saying I'm a shade tree mechanic and I haven't twiddled with this car or any for 12 years...
I hadn't started it for a year (yes I know that's a horrible thing)
It's summer and I thought I'ld clean it up and take it out get it legal inspection and blow the dust out
Charged it up..
Tried to start it .. cranked it a few times..
then it started to fire up..
cranked it again.. fired up
idled funny for a sec and then started to stall
tried to stop it by giving it gas but it shut off
I pumped it 2 times and tried to restart
nothing just turns over and over
took the breather off and gas is everywhere
dripping out of the nut/spring adjustment on the right side if ur facing it
Obviously it's flooded..
I tried drying everything off and not pumping it just to start it
does the same thing cranks but won't turn over and sprays gas out
of the hole in front of the valve opening

Any suggestions on how to get it started or what could be the problem ?

it's a 1987 camaro 305 4bbl
5 speed everything is pretty much stock
garage kept with 120,000 miles
