Description
Overview:
This Genuine Stihl cylinder base gasket is an OEM sealing component for the 2‐stroke engines used in the Stihl 046 and MS 460 chainsaws. It sits between the cylinder and crankcase to maintain airtight sealing and correct compression, which are essential for reliable starting, stable idling, and full power under load. The gasket is 0.3 mm (approx. 0.012 in) thick and is made from a durable, fibre‐reinforced gasket material that resists heat, fuel, and oil. Precision cut to the original pattern, it aligns with ports and stud holes for a straightforward, accurate fit. OEM part number 1128 029 2304, it helps prevent air leaks and fluid seepage, supports correct port timing spacing, and contributes to long service life of the top end.
