Still stalling after carb rebuild. ???

so the rebuild on the Holley 1920 is complete, put it back on the Dart, she fired right up and sounded waaaaay better than before the rebuild but although she sounded smooth and ran without stalling for twice as long as before the rebuild......she still stalled. Same issue as before, once stalled she won’t fire up without you’re foot on the glass and once you release the pedal she immediately stalls. Takes a long while before she will fire up again with pressure to the pedal. Playing with the idle adjustment screw doesn’t seem to make much of a diff although I’m a novice and this was my first rebuild. Pics posted......I question the linkage on the float bowl vent as the other end of that rod just hangs there and I don’t see how it does anything without being connected. That is how it was when I removed the carb I originally. Thoughts on any or all of this?

Default for the idle mix screw is 2 turns out up until 1969 then it is vacuum set to 14.2 to 1. Check the float level via the economizer diaphragm opening, should be 27/32th from the machined surface to the gas surface. Is the bowl vent operating lever missing?
