Description
Overview:
The Carburettor C1Q-S257A is a genuine Stihl replacement part for the MS 192 T and MS 192 TC-E chainsaws. It is a diaphragm-type carburettor with a robust, die-cast aluminium body and steel/brass fittings, designed to meter and mix air and fuel accurately in 2‐stroke engines. By restoring correct fuelling, it helps your saw start reliably, idle steadily, and deliver consistent cutting performance.
