Renew Your Chainsaw Performance with the Savior MS170 Rebuild Kit

The Savior MS170 Carburetor Rebuild Kit is designed to refresh Stihl models 017/018 and MS170/MS180 chainsaws that use ZAMA RB-66 RB-77 carburetors. This all-in-one kit provides a complete set of components so you can restore fuel delivery and responsiveness without hunting for individual parts. The build quality emphasizes reliable operation under real-world conditions—whether you’re pruning, limbing, or felling small trees, a well-tuned carburetor can help your saw perform more consistently.

What makes this kit stand out is its broad compatibility. It targets ZAMA RB-66 and RB-77 carburetors and pairs well with various related carburetor models, including many C1Q family configurations. If you’re maintaining older equipment or stocking up for field service, this rebuild kit offers a practical solution that aligns with common Stihl and ZAMA configurations.

Key contents and configuration are designed for straightforward rebuilds. You’ll receive essential gaskets, diaphragms, and wear parts that commonly wear with time and use. In practice, this kit can help restore the carburetor’s sealing and fuel metering, supporting more stable idle, steadier throttle response, and reliable startup in typical working conditions. While outcomes can vary by engine condition and maintenance history, many users report smoother operation after completing a rebuild with the included components.
