Carburetor linkage Questions for 67 Dart

str12-340 The pictures are great. After reviewing them and other pics that have been sent, I think my linkage setup is essentially correct. Traced it from the carb to the trans and visually it all seems to be there (auto 727). May need a minor throttle cable adjustment but not sure about that one yet.

What I did find was that at WOT my secondary jets aren't opening or even getting gas from what I can tell looking down into the carb (Eddy 1406 model and old) with the engine off and manually working the throttle at the carb.

I don't have the engine history on the car but it's been like this since I bought it and I'm just now getting around to it.

I was expecting to see the butterflies open at WOT but they don't move. The primaries move and I can see the gas.

Is the carb shot? What am I missing?
