Description
Overview:
The C1Q‐S191A carburettor is a Genuine Stihl replacement part for MS 181 and MS 181 C petrol chainsaws. Built with a durable die-cast metal body and precise internal metering components, it controls the fuel and air mixture so the engine starts reliably, idles evenly, and delivers consistent power.
