A lot of instructions from assorted sources use the same term, but for the stock carb on our engine it is more correct to call it a fuel mixture screw.
Well, actually, your word usage isn't wrong as the SSM calls the screw a Pilot Air Screw and a Pilot Screw, depending on the particular Spec sheet you are reading. Just a bit of confusion that I guess comes from changes over 2 decades. In the earlier models, or on a few foreign models some jets exist that aren't even present now.
However, I guess that I was wrong and had the actual operation backwards. I didn't realize the "filter vs. engine side" differentiation. I appreciate your explanation. It's certainly more intelligent, anyway.
Still though, the adjustment instructions that I have read and used, do not concern "rich or lean" they only concern finding the smoothest running position located mid point between "in and out".
On ours, the adjustment was simple and hasn't been touched in a couple years. We don't ride around with screwdrivers like some kind of newbie.
