Overview

The SIMPERAC FS 55R Carburetor Air Filter Cover Kit offers a comprehensive replacement solution for STIHL weed eaters and KM kombi motors. Built to mirror the layout and function of original parts, this kit combines a carburetor with essential filters and seals to support reliable, everyday operation.

Key compatibility

Designed for a broad range of STIHL models, this kit supports several FS-series brushcutters and KM kombi units. It accommodates widely used variants such as FS38, FS45, FS46, FS55C and FS55R families, plus KM55R and KM55C motors. Because STIHL can ship two different carburetor versions for the same model, please compare your current OEM and appearance to ensure the correct match before purchasing.

  • FS38, FS45, FS46 family (including FS45C, FS45L, FS45CE-DZ, FS45CEZ)
  • FS55R, FS55, FS55C, FS55RC and related FS55CE/FS55DZ variants
  • KM55, KM55C, KM55R and KM55RC kombi motors

What’s included

The package consolidates a ready-to-install carburetor alongside a full set of consumables and fittings, making maintenance easier in one order. Included items:

  • 1 carburetor
  • 2 air filters
  • 2 fuel filters
  • 2 gaskets
  • 1 spark plug
  • 1 primer bulb
  • 2 fuel lines
  • 1 air filter cover kit

Notes on installation and fit

For the best result, check the OEM part number and visual appearance of your current carburetor. This kit is designed to align with OEM 4140 120 0612 in the listing, and it may not fit machines that use a different variant such as C1Q-S282 4140 120 0623. If in doubt, compare the carburetor body shape, mounting points, and connection hoses prior to purchase, and consult your user manual for proper assembly steps.

Why consider SIMPERAC

Choosing SIMPERAC can offer an OEM-style replacement with a comprehensive parts set, reducing the need for separate purchases. The included filters and gaskets can simplify routine upkeep, while the complete kit provides a single solution for parts that wear over time. Think of this kit as a practical upgrade that may help keep your STIHL trimmer running smoothly through the seasons.
