Choke driving me crazy!

Hello, new member but have been lurking for a few years since I got my Dart.

I’m having trouble adjusting the divorced choke on my 71 Dart. I can’t seem to get enough range out of it. If I adjust it so that its closed when the engine is cold, it won’t fully open when the engine is hot. If I adjusted it so that the choke is fully open when the engine is hot, then when the engine is cold, the choke is only half to ¾ closed. I’ve bent the choke rod back and forth to shorten and lengthen it, and have also turned the little screw that turns the spring on the choke back and forth, but can’t seem to get it dialed in.

The best I can seem to accomplish is having the choke adjusted so that its fully closed when cold, so that the engine starts easily, but when hot, the choke is like 80% open and the fast-idle screw is still resting on the fast-idle cam.

Last night I had adjusted the choke so that when the engine was hot, it was fully open and I thought I had it diad in, but when I tested it out this morning, (72 degree ambient temperature) pushing down the throttle only caused the choke to be about 3/4 ‘s of the way closed. Maybe it’s too warm outside for the choke to be fully closed? I don’t know, but any help would be appreciated.
