Description
Overview:
This genuine Stihl decompression valve is a small, robust metal component that helps your chainsaw start more easily by temporarily releasing pressure from the combustion chamber. Designed specifically for Stihl petrol chainsaws, it is a direct fit for the MS261 and MS261C. By lowering cylinder pressure during cranking, it reduces the pull force needed on the starter rope and lessens strain on the starter system. The valve features a precise 9.8 mm thread diameter for secure installation and reliable sealing. Built for tough use, it withstands heat, vibration, and frequent starts common in professional and domestic work. As an OEM part, it offers correct fitment and dependable performance to keep your saw starting consistently and running efficiently.
