Someone please help me

So first things first..my 318 is in a mustang. Ik blow me up on why the hell I'd do that but I seriously need help, this place seems friendly and like it has smart ppl to help. So the 318 that is in my 2002 Mustang that was an original V6 Mustang. It is stalling whenever I barely tap the throttle, it idles great, it revs great, it even drives great but as soon as I try to barely go up the RPM it tries to stall on me. even some occasions where I would try to back out of somewhere and it will just shut off. I don't know what the issue is I've tried ignition, I've tried timing, I tried a little work with the carburetor but don't know much about it, it's a stock 2 Barrel. At first I thought it was the 727 transmission that also came with the engine that was messed up and causing parasitic losses but then again this engine puts out roughly 200 horsepower and I'd be willing to bet 30 horsepower could spin this transmission, There is no backfire out of the carburetor there is no fueling issues that I can see although I haven't revved the engine and looked directly over the carburetor as that seems kind of unsafe but I'll do what I have to if I need. Also second question the two screws that are on front of the two-barrel carburetor that came stock with this engine are to adjust fuel enrichment for idle right?
I applaud you for diving into this project. You'll learn a lot through all of this! None of us were born knowing what we know, but had to start somewhere. Be a sponge and soak up what this forum has to offer you & have fun!
