I'd suggest it is the choke butterfly not going open, especially if at starting it, it idles fine. Black smoke is way too rich fuel mixture. You can remove the choke, but I'd suggest (you should have had some fairly detailed instructions in the carb kit) fix it correctly, it is difficult to start a could engine without a choke.
There also besides mechanical rod measurements for the fast idle, and choke, setting for the thermostatic pulloff. Best way to troubleshoot your problem is to duplicate starting, driving (if still won't run properly, then removed the air cleaner to see if the butterfly is closed.
I just did a Rochester 2GC (first one in about 30 years), and had to "work" with adjustments.
