Carb for a 340?

The edelbrocks are know for percolating the fuel out and being hard to start after they sit for a while. Its perfectly normal because todays fuels evaporate out of carburetors. The Holleys accellerator pumps draw fuel from the bottom of the bowl so even if most of the fuel evaporates out the car will still start right up. I run the Eddie 650 AVS and love it except for the fuel percolation issue.
