What are the settings on stihl AV 28 carburetor from factory?

The Stihl AV 28 carburetor typically has three main settings: the low-speed (L) mixture screw, the high-speed (H) mixture screw, and the idle speed (T) screw. Factory settings usually recommend starting with the L and H screws set to about 1 to 1.5 turns out from fully seated, and the idle speed screw (T) adjusted for smooth operation. However, it's essential to consult the specific equipment manual for precise factory settings, as they may vary by model and application. Always make adjustments based on performance and environmental conditions.
