Description
Overview:
This cylinder gasket is a Genuine Stihl OEM part designed for small two‐stroke chainsaws, including the MS 150 C and MS 150 TC. Made from a heat-, fuel- and oil-resistant fibre‐reinforced composite, it sits between the cylinder and crankcase to create a secure seal. A correct seal preserves compression and crankcase pressure pulses, which are essential for clean running, easy starting and full power output. The precision profile matches the original factory specification for reliable alignment of ports and fasteners. Suitable for routine maintenance or a top‐end refresh, it helps prevent air leaks that can lead to lean running and premature engine wear. Manufacturer Part Number (MPN): 1146 029 2300. Genuine status: Genuine Stihl part.
