2-Stroke Direct-Fit Carb Assembly

Replacement carburetor assembly for Stihl BG86, SH56, SH56C, SH86, and SH86C leaf blowers. Built to replicate the C1MS261B unit’s external footprint, internal passage routing, and fuel metering logic. Supports proper air-fuel mixing essential for efficient 2-stroke combustion — improving cold start reliability, smoothing out idle fluctuations, and delivering linear throttle response. Installs using original fasteners and fuel lines; final tuning aligns with Stihl-recommended idle speed and mixture settings. Suitable for preventive replacement during annual servicing or reactive repair following performance loss.
