Description
Overview:
The Carb Intake Gasket is a genuine Stihl spare designed to seal the joint between the carburettor and the intake on selected handheld machines. Made from fuel- and heat-resistant fibre composite, it maintains an airtight seal to prevent unmetered air from entering the engine, helping to preserve correct fuel mixture, smooth idling, and reliable starting. This gasket suits popular Stihl models such as the SH 55 and SH 85, along with selected BG blowers and the BT 45 hand drill. As an OEM component (Part No. 4229 129 0900), it offers the correct thickness and port shape for a precise fit, reducing the risk of air leaks after servicing or carburettor removal. Supplied as a Genuine Stihl part for dependable compatibility and long service life.
