Slant 6- Idle and Running

I've read through a number of people with similar issues but mine seems to be slightly different, I apologize if anyone thinks it was too close to other peoples questions...

The Car is a 72 Duster with 225, 1920 carb, just been picked up. I am trying to diagnose without throwing too many parts at this motor. So far I've replaced all vacuum lines and have a balast resistor and ignition coil in the mail since they are cheap. Car had old gas it in when I got it and didn't have a fuel filter either, both of those rectified.

Problem... Car won't idle without some throttle. The car turns over and starts, once started it will run with light throttle and sounds healthy...until warm. It won't stay on unless there is light throttle, if I try to give it more throttle, it stalls like its not getting fuel. Once the car warms a little, it stalls and will not start. The choke seems to operate fine, except once its open/cars warm; the car stalls and will not start. Strong smell of fuel throughout all of this but it's not exactly acting rich either. I can't tune the carb well because I can't get the car running long enough, but changes I do make to the idle mixture and idle speeds don't much of a difference (even extreme changes). One thing is the fast idle screw and cam seems extremely 'loosey goosey' with lots of slop, are there any photos/videos out there showing how the 1920 linkages are all meant to operate as it's hard to tell if mine is correct.

Balast resistor faulty?
Faulty carb float?
Carb problems, in need of a rebuild after some varnishing from old gas?

Thanks in advance for you help!!

TLDR: Slant 6 only starts from cold and wont idle well, cant gain revs without stalling, once warm it stalls and won't start.
