I had this same problem. I fiddled around with everything in the
carberator and tried the pressure regulator. The pressure regulator
could not be turned down to a low enough pressure without starving the
carberator for fuel. I bought an electric fuel pump rated for the
correct low pressure and it has run like a dream for two years. I was
able to lower the float to keep off camber flooding to a minimum.
Another trick if your replace a one barrel with the Weber is to turn
the carb. 90 degrees which puts the bowl stick out toward the drivers
side. The thing will not flood out even when the wheels start coming
up (I don't like to talk about how I know that). I bought a Purolator
universal replacement pump at Advanced with the right pressure rating.

There are different regulators for different ranges of fuel pressure. The
one I recommended is rated for 1-4 PSI, which will not restrict the fuel
flow like the higher pressure regulators will. Most regulators are rated to
go down to about 4 PSI, and trying to get them to run at 2 PSI or so will
cause a fuel starvation problem.
