New Project - '71 Plymouth Valiant

Alright... Update time, and another problem (DONT THEY EVER STOP!?!):

Cranking issue was simple... bad cells in battery. It was holding +12v while not cranking due to overcharge from before, but two bad cells killed the cranking amps.

Now... she will start, but will not stay running when I let my foot off the gas. Here's a list of all the stuff I know:

Fuel Pump is good.
New Fuel Filter.
New Spark Plugs and Wires.
New Battery (800+ CCA/1000+ CA), I believe car needs 440 CCA to crank.
Starter is good, had it tested at O'Reilly's.
Charge System Wires Replaced, good connections at all points.
Fusible Link is good.

Carb Flap (unsure of actual name) is seized open (getting too much air?). There is a line tied from the flap mechanism on the outside of the carb leading into the exhaust manifold, slightly bent and will not move. I'm unsure if this piece is supposed to move due to something in the motor?

I am unsure what the problem could be, i don't know if the timing is off, or the carb is the problem. Possibly throttle line too loose? If you guys have any ideas, please let me know.

Also, I need to find the bulkhead connector ends, so I can rewire everything else under the hood (I would like to clear as many potential issues as possible - and I'm finishing my electrical class right now, so it's a good time to do the work). I cannot tell if these are the correct ends (Wires in bulkhead are pretty old... don't want to pull one and risk killing the car until i know I can fix it on hand):


Thanks guys, as always - any help is appreciated!
