bad coil or ECU ?

Not seeing a link?? But I will look at this. Unknown for sure the choke is open all the way and it's getting plenty of fuel (obviously) lol I have adjusted the air fuel mix screws IN until it starts to run a little rough.. Then backed them back out a half a turn .. But some more info on the butterfly's would be appreciated .. Not exactly sure what to do with them ??

I'm gonna guess the butterflies are too far up the transfer ports causing it to run rich.Rich is great for a cold engine, but the warmer it gets the worse rich is.
And you plainly detailed all the rich symptoms.
So if you can't find the problem in the choke or the fuel level, then check the T-Port sync;see link below.[/QUOT
