How this cause it to run rich and not lean?
If you saw a lot of junk come out when you cleaned them there's a good chance there's more stuck somewhere.

Did you blow the passages out with high pressure compressed air?

At this point I would soak the entire carb in cleaner, and possibly have them ultrasonic cleaned.

It's possible the needles aren't seating properly - I'd replace them at this point. When you have the carbs off and turn them upside-down you should feel the needle seat before the float bottoms on the carb body. If that's not happening they might not be shutting the fuel off completely.
