Have you tried it with lower fuel pressure?

Subject: Carburetor problem
Hello,
I have a problem with a Carter 500 (BGT 4.2 Buick) flooding over in
autocross events that I am trying to solve. I am hoping someone on this
list may have an idea.
The problem seems to be gas pooling in the intake and progressively
getting worse during subsequent runs. It became quite evident after the
purchase of some racing tires. I suspect it is because the braking is
much more severe. I dont think its from cornering since the narrow
width of the bowl on the sides seems to be optimum for cornering.
The roughness and black smoke as a result of this condition clears up
after getting out on the highway and running with the secondaries open
for awhile. Then its good for another run as well as running great in
all other circumstances.
I have tried lowering the float levels. I also tried to adapt a Holley
390 but changed my mind because of the complexities.
I'm thinking about fuel injection for next year so my objective is to
try to modify this carburetor for now. Any suggestions?
