your rich condition is most likely a rich main jetting circuit ,more so than your premix ratio and /or choice. 520 main is huge for a zilla and you didnt say what your shes was jetted @ so cant help you there,tinkering with your air screw isnt going to drastically change shit if your plugs are very wet rich . drop those mains ,do a plug chop ,check your plugs for cardboard color and your plug strap for tempeture readings.
