Gas leak from airbox

[roost]

I'm working on a 80' 750 and noticed gas leaking from the airbox drain, usually after it has been riden a puddle of gas develops on the floor overnight and continues to leak.

I have cleaned the carbs, don't think it's a float problem. Wondering if this is a petcock problem given that the petcock seems shot, or improper venting?

Also, I only have two tubes connecting the petcock to the carbs, it appears that the vacuum is between the 1-2 carb on the front and the fuel line is between the 3-4 carb on the back, does this sound odd?

I'm new to these suzuki's and don't want to clean the garage floor everynight.
