Malossi 166 28mm dellorto phbh carb set up

hi all I'm going to be putting a 166 onto my px125 motor. I have already installed sip bearings and corteco seals along with a mazzucheli race crank. im wanting to bolt on a 166 with a 28mm carb but wondering what carbs settings should I be looking at. my exhaust is a twisted rods mk1 (like a rz revolver). any help would be greatly appreciated.
