Description
Overview:
This carburettor gasket is a Genuine Husqvarna OEM part for the 357XP and 359 chainsaws (MPN 503967601). It is a flat, fuel‐resistant gasket that creates an airtight seal at the carburettor mounting surfaces to prevent unwanted air leaks and fuel seepage. By maintaining proper vacuum and mixture control, it supports smooth starting, stable idling and consistent power under load. Built from durable gasket material suitable for petrol two‐stroke engines, it copes with vibration and heat typical of chainsaw use. Use it when rebuilding, servicing or refitting the carburettor to restore reliable performance and protect engine longevity. Designed to match the original dimensions for a precise fit on Husqvarna 357XP and 359, it is a straightforward replacement for worn or damaged gaskets.
