Running rich....To big of a carb or?

DOES it shut down with the idle mixture screws turned all the way in?

Yes I can turn the idle mixture screws in and cough the engine out.

However, while running at and idle around 750-800 rpm. If I turn the mixture screw in until it stumbles, and then back the screw out a quarter turn and repeat the same step on the opposite mixture screw. It runs good.... But I checked the position of the screws and at this point both screws are a half turn away from being fully seated. Not sure if that's right or not. But if I back them out any further than a half turn than i believe it will richen the mixture even more. And I'm aiming to lean it out.... Not richen it up

Well, I would say that if you can turn the idle mixture screws in....like you said.....and make the engine die, then I don't see why you can't make it lean enough at idle. You can lean it out to the point that it's stalling! I think it may be that your cam is just lopey and inefficient at idle, and maybe that's where the burning eyes/"rich" smell is throwing you off.

Wherever the screws are positioned to make it run good.....is good! I wouldn't be concerned if they're only 1/2 turn out from being seated. If it works, it works.....
