Bought my first mopar 73’ Duster and the bottom of the air filter pan is black (right above the carb). Any tips on how the 4bbl should be adjusted

Thank you both! I took a few more pictures of the engine and interior. It’s raining where I am so once it stops I’ll pull it out of the garage and take some full shots of it. Currently just barely fits in the garage because I hadn’t planned on getting another car anytime soon but just kind of fell in my lap. Not sure what that wiring mess is under the steering wheel yet but it has led light strips outlining the bottom of the car so I figure that’s it.
