Edelbrock mid throttle problem

Keep in mind the Eddy's are more easily adjusted with rods than jets too. Changing the jet changes both steps of the metering rod, changing the rod usually allows you to keep one step the same and gives you 2 or 3 options for the other step. Springs are easy to change too

TTC-

If you're fine at idle, fine at cruise, and fine at WOT, then the idle setting is fine, the primary step of the metering rod is probably ok, and the secondary jets are ok. I would look at the second step of the metering rod and the spring. You could try a stiffer spring to bring the second step in sooner, and/or make the smaller step on the metering rod another size or two smaller and see if that helps. If there's no bog or anything, the transition to the second step on the metering rod is probably taking place at close to the right time, it's just not enough of a step.

Opposite! Just like RRR said. Try a softer spring so you stay on the primary step longer. And maybe a larger diameter rod, at least on the primary step. The "lopey" cam probably means there isn't enough idle vacuum to keep the metering rods down on the primary step so you're going too rich. I'd try the spring first to make sure you aren't immediately going to the second step of the metering rod because of the lack of vacuum.

I run a Carter on my Challenger, actually have had a couple on there, and my g/f has an Edelbrock carb on her '55 Coronet and '71 F100. They're good carburetors, and I've found them to need a lot less adjustment than the Holley DP I'm running on my Duster. The rods and step up springs are super easy to change, no messing with gaskets or fuel at all. And usually you don't have to mess with the jets too much, although that requires taking off the top of the carb and messing with the gasket. Usually though the rods and springs can do most of the tuning. The only issue I've had with every Eddy or Carter I've had is that the fuel bowls will dry up after a couple days, so you have to crank fuel into the carb if they sit. The Holley DP seems more resistant to that.
