edelbrock 1406, running way rich, how do i tune them?

Ok so update:

I did the full rebuild today and to my surprise, i didnt screw it up. lol, well atleast not totally. I had expected that i would screw up badly, and be buying a holley on tuesday.

Anyways things i found once inside the carb:
1. Nasty carbon deposits everywhere. Two cans of carb cleaner and it was good as new.
2. Floats were way off the appropriate adjustment range for both the drop/level
3. A metering rod was bent and sticking. Now bent might be on me because i made a newbie disassembly error, but i was never rough/forceful with the top plate. So i suspect the sticking/bend was there beforehand.
4. The floats appear to have a slow leak. They didnt sink, but the floated *** heavy and given enough time i think they would've sank.

So replaced the busted parts, cleaned everything, set the base adjustments per. the instruction sheet, and installed it along with a new set of spark plugs. It fired up instantly and sounded healthier than ever. There wasnt the annoying bog that the car use to have when it was cold.
