Description
Overview:
The Metering Gasket for Stihl KM 94 RC-E is a genuine Stihl carburettor sealing gasket designed to restore and maintain correct fuel metering and airtight sealing inside the carburettor. Made from a thin, fuel‐resistant composite material (black), it sits between the metering diaphragm and carburettor body to prevent air and fuel leaks that can cause hard starting, poor idle, or flat spots. As an exact replacement for OEM No. 4149 129 0904, it matches the original thickness and port profile for reliable performance. Suitable for a wide range of Stihl brushcutters and hedge trimmers, including KM 94 RC-E and FS 94, it is a practical service item for routine carburettor maintenance on 2‐stroke Stihl machines used in garden, landscaping, and light construction work.
