Time for a new Carb

Not to hijack this thread, but I noticed that no one has suggested using the free AFB carb. Is it a dog? I have a Carter AFB on my 74 Dart and I think it's holding the engine back. I haven't rebuilt it, but here's some of the issues I'm having with it.

• Fuel bowls empty after sitting for a day, not boiling out I have a wood spacer.
• No vacuum on the manifold port at idle, acts like it's ported. The ported port works properly.
• Pretty sure there is no gas being fed to the secondary's when they open. They do open, but the 360 with an eddie intake just doesn't wake up like I expect. I have no idea how to check for gas being fed to the secondaries.

Should I clean and rebuild it or just replace it with one of the suggestions above?
