Looking to find out where my initial air/fuel mixture screws should be set at for this carb.  Thanks!

The idle mixture screws are set for best idle quality at the leanest settings.  This should happen around 2.5-3.5 turns out from seated with that carb number on a correctly tuned and good running stock engine.....Cliff

Thanks Cliff.  I will be contacting you in the very near future for a rebuild.
