Any recommendations on best steps for tuning carburetor ?
Found several excellent videos on valve adjustment and had no trouble performing same on this powerhead.
Did find generic Stihl Carburetor Adjustment.
In pictures below, see H, L and LA (Idle)
Online directions are like this:

Turn the high-speed screw, marked 'H' counterclockwise until it stops.
Tighten the 'L' screw all the way, then turn it one turn counterclockwise to open it.

Press the trigger of the machine to rev the engine. Adjust the 'H' screw until the engine does not cut out or sputter.
