Default jetting

Hi all
I have been trying to get rid of a sputter at small openings on the throttle and have tried 45 and 42 pilots,but with these pilots the air screw had no effect either in or out.Then i tried a 40 pilot and the air screw now worked but only at 3.5 turns out.
My jetting is 178 main,40 pilot,CEK needle 4th clip,sea level and the temp is around 9 C. Reeds ok.
Could i use a 38 pilot or am i too lean at the moment with my current settings,also is there anything else that could cause this type of setting.
Many thanks Macho
