Overview

Upgrade your Stihl trimmer with the Butom FS45 FS38 FS55R Carburetor Kit, an all-in-one replacement designed to cover a broad range of STIHL models.

Compatibility at a glance

The kit is engineered to fit multiple Stihl models, including FS45, FS38, FS55R, FS55, and KM55 variants, along with related FS55C/FS55RC families. Please note that certain KM55 configurations older than 2013 are specified for compatibility, so it’s wise to verify your model before purchasing.

All‑in‑One convenience

Designed to save time and money, this kit provides a single, cohesive replacement that can simplify maintenance and accelerate setup. It arrives factory‑tuned, meaning you can install it with minimal adjustment and begin testing soon after.

Quality and real‑world readiness

Butom emphasizes dependable operation by wet‑flow testing each carburetor variant to closely mirror how the engine behaves under real conditions. The result is a component that aims to deliver consistent performance across common tasks such as trimming grass, edging along borders, or clearing light brush.

What to expect in practice

• Factory tuning on arrival for a smoother install and quicker start‑up.
• All‑in‑one design that helps simplify maintenance and reduce separate part purchases.
• Broad compatibility across Stihl FS45, FS38, FS55R, FS55, and KM55 family models.

Usage scenarios

Ideal for reviving older tools or completing a quick rebuild when the standard carburetor shows wear. The kit supports a range of pre‑2013 KM55 variants, making it a practical option for mid‑range hedge trimmers and weed eaters seeking reliable, ready‑to‑use performance.
