Description
Overview:
This metering diaphragm is a Genuine Stihl replacement part that controls fuel delivery in the two‐stroke fuel system of your machine. Built from fuel‐resistant, flexible material to withstand regular use, it keeps the mixture consistent from idle to full load, helping your engine start easily, pick up cleanly, and run smoothly. It is a direct replacement for OEM No. 4149 121 4702 and is suitable for a wide range of Stihl brushcutters, hedge trimmers, and Kombi engines. Ideal for routine servicing or a repair when the original diaphragm has hardened, torn, or lost flexibility, it helps restore reliable performance.
