You seem to already know that you're running WAY lean. I'm a little confused; are these stock carbs with a vito's needle or vito's carbs? Anyway, sounds like a pretty close set-up to mine. Idle screw should start at 1.5T from seated, you need to richen up your low jet, I'd say 27.5 but you could try the 30. I'm gonna assume you have 6-slot vito's needles and you're 3rd down from the top. Move the clip to the fourth position to richen the low-mid transition too and you should be OK. You should do a plug chop to confirm that the high end is OK.
