Description
4237 120 0615 STIHL Carburetor C1Q-S292B – Genuine OEM Carburetor Part
The STIHL Carburetor C1Q-S292B (4237 120 0615) is a genuine OEM fuel system component designed to deliver precise fuel-air mixture control for select STIHL professional hedge trimmers. Engineered for reliable starting, smooth throttle response, and consistent cutting performance, this carburetor restores factory-specified engine operation.
Over time, carburetors can develop internal wear, varnish buildup, diaphragm fatigue, or metering issues due to fuel exposure and extended use. Symptoms may include hard starting, surging, poor idle, hesitation, or reduced power. Replacing the complete carburetor with the correct OEM assembly eliminates guesswork and restores proper fuel calibration without requiring a rebuild.
Manufactured to STIHL factory specifications, this genuine carburetor ensures correct jetting, metering accuracy, and long-term durability under demanding professional conditions.
