Carb adj. on stihl 025

[TalonSharp]

Newbie here...got my first Stihl, but no manual....using Durex @ 40:1
running a lttle rich at hi-speed, so where is the hi-speed mix adj.?.
Appears to be only an idle mix and idle speed adj. on the right side.

Believe it or not, those new one screw adjusters are not an improvement. That's all you got......one screw to adjust both your low and hi. Imagine that new technology !!! It's like having a Low/Drive/Reverse gear in your car. Prevents us from running our saws too lean so they say.
My low tech advice: Just mess with it til it levels out (if it ever does).
