Overview

The Hipa FS 91 R carburetor is engineered as a precise, direct replacement for STIHL 2‑cycle trimmers and kombi engines. It’s designed to mirror OEM specifications, aiming to restore steady fuel delivery and reliable cold starts without the premium dealer price.

Compatible with a broad family of STIHL units, including FS89, FS91, and FS111 trimmers; KM91 and KM111 kombi engines; and HT102/HT103 pole pruners, this kit is practical for both pros and homeowners who want a single, ready-to-install tune‑up option.

What’s in the kit

  • 1 Hipa FS 91 R Carburetor tuned for STIHL compatibility
  • 1 air filter
  • 1 fuel filter
  • 1 primer bulb
  • 1 fuel line
  • 2 spark plugs
  • 2 gaskets
  • 1 screwdriver for installation

The box consolidates commonly replaced parts for a streamlined maintenance experience. The replacement aligns with OEM references 4180 120 0618 and 4180 120 0615, making a swap straightforward for many service scenarios.

Performance and installation

Replacing an aging carburetor can address symptoms like hard starting, rough idle, and stalling under load. The Hipa FS 91 R is designed to support steady fuel delivery and smoother engine response as you work through grass, brush, and edging tasks.

Whether you’re a DIYer or a professional, installation is intended to be straightforward: match the old unit, apply standard adjustment procedures, and proceed with routine checks. The build uses wear‑resistant materials to withstand outdoor job sites and temperature changes across seasons.

Key benefits you may notice

  • More reliable starts in cooler weather and after fuel system work
  • Consistent idling and smoother cuts with even engine breath
  • Improved fuel delivery that supports steady power under load
  • All-in-one kit reduces the need to source separate components
  • Durable construction designed for outdoor use and repeated maintenance
