The Edelbrock (Carter AFB) is a superb carburetor right out of the box. I run a Holley, but it's not exacly what you would call a streetable setup. All of my past cars had Carter AFB's on them, and I never had any troubles with them. One of those kits that give you extra meetering rods and springs is a very good idea, but you shouldn't have a problem just the way it is. And, for street use, I would get the electric choke version.
