well the only place fuel is stored while the car is shut off is in the bowls..so its gotta be linked to that...it can leak around a bowl and run to other parts lower on the carb making it look like its coming from somehwere else..
i say start with bowls and make sure needle seat was not stuck while the car was running causing hung up floats with too much extra fuel in bowls.
