FAQ

This kit is compatible with Stihl 017, 018, MS170, MS170C, MS180, and MS180C chainsaws.
This carburetor replaces OEM part number 1130-120-0603 and is a direct replacement for Zama models C1Q-S57, C1Q-S57A, and C1Q-S57B.
You likely need a new carburetor if your chainsaw is hard to start, idles roughly, stalls during operation, or lacks power under load. These issues are often caused by internal diaphragm degradation or clogged fuel passages, especially if the saw has been sitting with fuel in the tank for an extended period.
Installation is straightforward and typically takes about 15 to 30 minutes for someone familiar with small engine maintenance. You will primarily need a screwdriver (flathead and/or Torx, depending on your specific housing screws), a socket wrench for the air filter cover, and pliers for the fuel line connections.
Since you are already opening the saw, it is a good practice to inspect the fuel tank vent and the impulse line for any signs of cracking or dry rot. Replacing the fuel and oil lines included in this kit is recommended if the existing lines feel stiff or brittle, as this prevents future air leaks and fuel delivery issues.
No, this kit is specifically designed for the older MS170 and MS180 series. It is not compatible with the newer MS171, MS181, or other strato-charged models, which utilize a different carburetor design.
