LAHDEK Carburetor For STIHL FS38 FS45 FS46 FS55 FC55 FS74 FS75 FS76 FS80 FS85

Replacement carburetor for STIHL trimmers

This new replacement carburetor fits STIHL trimmer models FS38, FS45, FS46, FS55, FC55, FS74, FS75, FS76, FS80 and FS85. It is a 2-stroke petrol engine component designed to restore correct fuel metering. The part suits owners and repair shops servicing these specific brushcutters and line trimmers. It is not intended for 4-stroke engines or models outside the listed series.

Sustained-load behaviour

The carburetor maintains a steady air-fuel mixture during extended cutting sessions at full throttle. Consistent metering prevents lean hesitation when the trimmer head is under continuous load from dense vegetation. Stable idle recovery follows high-speed runs without hunting or stalling. The component supports reliable operation across the full operating range of the compatible 2-stroke engines.

Thermals, noise and power draw

As a passive fuel-system part, the carburetor adds no electrical draw and produces no mechanical noise of its own. It does not alter the engine's thermal characteristics beyond delivering the calibrated mixture for which the original power unit was designed. Normal operating temperatures and sound levels remain unchanged when the carburetor is correctly adjusted. No external power source or cooling provision is required.
