Description
Overview:
The Carburettor WT-286A is a Genuine Stihl Part for mid-size 2‐stroke chainsaws, engineered to meter and mix fuel and air accurately for clean starts, steady idling, and strong acceleration. Built around a robust die‐cast aluminium body with precision-drilled passages, it is designed for the demands of forestry, landscaping, and domestic cutting work. This diaphragm-type carburettor suits machines that are used in varied positions and conditions, providing reliable fuel delivery independent of tank level. It is supplied to match Stihl specifications under MPN 1123 120 0615 for direct replacement and correct fit. Compatible with popular models including MS 250 and MS 250 C, it restores lost performance caused by wear, dirt ingress, or a failing metering/pump diaphragm.
