Chinese BBD Knockoff...?

That's what I'm thinking . Its the wife's uncle he's 85 beleive it or not and still playing with hot rods, its a 49 Plymouth coupe. Im just trying to help him out. I saw it running and immediately said "Its running rich" I think its dumping fuel bad. His no nothin neighbor is condemning the engine I said "that black smoke isn't oil burning..." the rationale is "the carburetor is new" I'm saying "I don't trust knock off parts..." Im planning to go over my BBD just as a test carb for now to prove to the old fella his "new" carb isn't working right.
It could be a fuel pump as well. A buddy bolted a new Car Quest pump onto his 440 and it put out 15# and the carb wouldn't keep up with that.
