I had one of those POS carburators on my 56 Chevy w/350 engine and trans. That was the first thing I dumpsterized and replaced with a Holly w/vacuum secondaries. You might want to lower the fuel pressure, which may be the cause of the extra fuel dripping from the carb. It really only needs to be 3.5 - 4 PSI and will run you car's setup just fine, even on a dragstrip...
