Description
Overview:
This Carb Adaptor Seal is a Genuine Husqvarna part designed to restore an airtight joint in the intake system of small petrol chainsaws. Made from a fuel- and oil-resistant elastomer, it fits precisely between the carburettor adaptor and adjoining intake components to stop unmetered air entering the engine. By preventing air leaks, it helps stabilise idle, improve throttle response, and support easy starting. It is a direct-fit replacement for the specified models, including the Husqvarna 236 and 120 Mark II, and is supplied to the original equipment specification for material, shape, and fit. Use it during routine servicing or when air leaks are suspected to maintain reliable performance and protect the engine from lean running. OEM reference: 577 63 65-01.
