A/F Screw

I cant find what the factory setting is for the A/F Screw on my carb. Anyone know how many turns out is factory? Does turning in the screw restrict air or fuel? Trying to dial in the carb and I have a feeling my A/F screw may be out of adjustment. I can put my hand partly over the airbox intake and restrict the aiflow and it seems to run better (just reving it while setting about 12k rpm near redline) when ever I put it in gear and take off it maxes out at 7-8k rpm. My theory is I'm restricting the air enough, but once I put a load on the motor (200 lbs of me) its not getting enough air. I've changed the "clip" on the needle valve to run lean and rich it seems to run better on the lean side (I'm about about 2-3k ft above sea level)

Thanks in advance
Mike
