With the info you provided there isn=E2=80=99t to many =E2=80=9Ccauses=E2=
=80=9D that would fit those parameters.
Fuel on the ground under the front of the car---very over rich situation a=
t the carbs, likely a float needle stuck open. Not sure if the fuel spill h=
appened when the ignition was on or off.
When it does start, runs rough. You didn=E2=80=99t mention if it was belchi=
ng black smoke out the tailpipes. Could be lean or rich but since you ment=
ioned the spark plugs looked OK suspect lean condition ---
Suspect clog at the float needle. It only takes a very small flake of rust =
or crud to block them or hold them open.
The carbs really don=E2=80=99t care if a bit of air is being sucked through=
the fuel line as long as the carb bowl stays at the proper fuel level in t=
he float chamber.
Did you collect a sample of the fuel when you ran the pump with the fuel li=
ne disconnected? Wasn=E2=80=99t sure what =E2=80=9Cran clear=E2=80=9D meant=
other than no bubbles. Was it a visual observation or inspected sample.
I=E2=80=99m leaning towards a rusty fuel tank or accumulated crud in the fu=
el system. As others mentioned, a filter between the pump and carb will rem=
ove the offending substances before it gets to the one place that makes the=
engine act up, fuel wise.

I guess I wasn=E2=80=99t too clear on something in my first post I only sme=
lled raw gas once and it only leaked fuel once. Since then I have searched =
for some source of fuel leakage but can=E2=80=99t find any. I was thi8nking=
that it might be sucking air as well as gas through some hole in tank to p=
ump lines, but when I checked the fuel delivery it ran clear with no air bu=
bbles in the gas..
