Holly 1920 carburetor adjustments?

It only smokes (black) a little when it's first started but when it's warmed up and I give it a good rev the exhaust smoke it barely noticeable. Sorry I'm 24 and not used to how these old cars are supposed to smell/act and the sounds they should and shouldn't make haha. Grew up in the wrong era sadly.
I'm not sure what's in the links SSD posted, but click on them & read, then check the obvious like vacuum leaks at the carb-bad hoses-stuck PCV-manny gaskets-etc.
