Have you adjusted the choke thermostat so the choke barely closes tight when the throttle is moved at ambient temperature?

Yes, it's open a small slit when cold and off....when the car starts and builds up RPM, it opens more automatically.....if I don't touch the throttle at all, it will warm up at higher idle ect ect.  But the instant I tap the throttle it nearly opens entirely, and I'm even talking within seconds to 10s, 30, a min. There's no gradual idle decrease as the choke warms up as it should be...

it's the strangest thing cause everything snaps shut and closes properly and tight with the thing off.
I have even been turning it to the "Richer" position (tighter)in stages thinking it required more tension/time to open, and nothing.
It doesn't make any friggin sense.

Ok I will give it a go, but if memory serves me correctly, it doesn't like starting completely shut...

But will this explain why it drops OFF completely seconds after starting AT high idle? 

I wish I could send a video, it describes everything

I'm not familiar with the Edelbrook carb, but from what you've stated it seems the vacuum through the main body is overcoming the spring in the choke body.  I suggest checking inside the choke housing, the tab that the choke coil attaches to the choke linkage may be the issue.

That's exactly what I was thinking, but that spring is tight. Snaps shut.....and I can't adjust it any tighter otherwise it won't open all the way....

As far as how it grabs the linkage, it was just the style that rests against it, so thinking as you are, I made a loop so it grabs the pin-------no room for it to travel independently.

Not yet but my experience with eddy carbs is to set them up per their obstruction and/or double check your work against their instructions for best results.

Did this just start happening or after some carb work? Perhaps Linda Blair established residence in your carb...

At this point, I'd call edelbrock tech support. They have an 800 number. Let them scratch their heads and give yours a rest. To me, sounds like something wasn't assembled correctly since it's been like this right out da box. I'd go so far as to take pics of the choke linkage for them to look at it. Worth a shot especially after what that carb cost you.

No, Incorrect.
The issue is NOT the choke CLOSING.......it's staying closed while the car is started and when it's running.

Car off, the choke literally opperates perfectly, snaps shut, idle screw is resting at the highest part of the cam, the flap is tight and springs back closed if opened.

When the Car is Running, and this can be immediate, if the throttle is tapped (hoping to reposition the choke to a slightly lesser cold start-high idle) it just drops the Cam and the Choke Plate Opens entirely.

If you shut the car off, tap the gas it shuts again....makes no sense!

From what I have read it sounds as the ele choke is not set up correct. When a ele choke is working properly you can turn it clockwise and it will  start to close the flap, or counter clokwise and it will open it. It does not need to be set farther than just closed.  The 12v key on will heat the spring and start to open the flap in just a couple of minutes. if set up right the choke can pull off of the detent and the carb will drop down to idle. Do all of the adjusting with the car off and  carb set at WOT . you should be able to open and close the flap just by turning the black choke mod clockwise or counter clockwise. If this isnt happing then the spring inside is not on the tab ( there is a tab inside that hooks on a flat tab that is connected the the flap by a short rod) or the rod is not on the back side and is hanging up. 
let me know I am pretty good wit elde carbs and live in the NW where we need chokes.

Yes I could have been mistaken on the WOT but its been a while. I just remember something about it hanging up? I too will look. found it it was for ajusting the fast idle screw. Im bad. 
But realy the choke should not "snap shut" as he is discribing
