The Carburettor C1Q‐S57B is a genuine Stihl OEM replacement for small petrol chainsaws, built to restore clean running and consistent power. It features a robust die‐cast aluminium body with precision‐machined fuel and air passages that meter the mixture your engine needs under load and at idle.

Suitable for professional users and home owners who want dependable performance from their Stihl chainsaw.
