You need to diagnose and relate the rich condition to the particular throttle position where it occurs, that will dictate which circuit is overfueling.
did you increase the size of your pilot jets as well as shimming the needles? With giant main jets?
Overfueling condition can be directly attributed to poor setup/jetting decisions (more fuel is better....everywhere....(NOT)
I divert, anyway you need to isolate the offending circuit and @
jkv45 is on the money...pilot screw adjustment is a required, standard tuning procedure.
I'd advise to adjust the pilot screws first...progress from there.
Syncing with an accurate, precise pro manometer too.
