Pilot Screw "Stock" Settings are baseline.. Doesn't mean it's correct

Apparently mines are supposed to be 1¼ turns out, but that is way too lean.

I actually have mines out 1¾ turns

Well that's a start

Are they fuel screws or air screws?
(Engine side or air box side of the carburettor)


I'm gonna presume they are fuel screws though, Try turning them in ½ a turn each which should lean it out.
