Hey everybody...
 
Short story: I have gas spilling out of my front carb overflow pipe.
 
Long story: I drove the car to the gym tonight (5 miles) and when I pulled into 
the parking spot, the car was stalling out and begging for gas. I could smell 
gas, but not see any underneath the car, although it was pretty dark. 
 
So I go into the gym, work out, come back out expecting to have to call a tow 
truck, but the car starts up pretty rough and zooms to life when I give it 
heavy gas. I drive home and it's driving great at speed, but when I stop at a 
light it starts to sputter and wants to die unless I stomp on the gas.
 
I putter home, pull in the garage, pop the hood and the front carb overflow is 
GUSHING gas. My garage reeks. My HOUSE reeks. 
 
2 things:
 
1) I feel happy to be alive
 
2) Is this as simple as buying a new float shut off valve?
 
These carbs are recently professionally rebuilt and are PRISTINE (+- 500 miles 
on them). I open up the float chamber and everything looks fine. The shut off 
valve appears fine, but I don't know exactly what I should be looking for on it.
 
I put in a new fuel pump 2 weeks ago, and this is the first time I have run the 
car for than a couple of minutes here and there. I initially thought that there 
was a problem with the fuel pump install (air getting in the line or something. 
I have noticed that the fuel filter doesn't completely fill up with fuel. Is 
this normal?), but when I saw the gushing fuel, I figured that it is pumping 
fine.
 
Anyway... You're all saying, "You idiot! The answer is obvious!" and I'm 
saying, "Please tell me what to fix."
 
Ideas?
