Description
Overview:
The Carburettor C1Q‐S85C is a genuine Stihl OEM replacement for selected mid‐size chainsaws, including the MS 250 and MS 250 C. Built with a robust die‐cast aluminium body and precision metering components, it controls the air-fuel mixture in the 2‐stroke engine so the saw starts reliably, idles smoothly, and delivers steady power under load. This unit is designed specifically for these models, matching the original linkage, fuel line positions, and mounting points for a straightforward swap with a worn or contaminated carburettor. Using the correct Stihl carburettor helps protect the engine from lean running and restores cutting performance for regular maintenance, firewood processing, and site work. Genuine Stihl part number 1123 120 0631.
