Carbhub MS170 Carburetor

This carburetor is designed as a direct replacement for Stihl MS170, MS180, 017, and 018 models. It is specifically engineered to match the C1Q-S57A carburetor type used in these saws.

You will generally need a basic set of screwdrivers, a socket wrench, and potentially a pair of pliers to remove the fuel lines. While the installation is straightforward, having your chainsaw's service manual handy is recommended for reference.

While these units are often pre-set, you may need to perform minor adjustments to the low and high-speed mixture screws once installed to ensure your specific engine runs smoothly. It is best to test the saw at idle and under load to see if fine-tuning is required.

Common indicators include difficulty starting the engine, inconsistent idling, or the chainsaw stalling frequently during operation. If you have already cleaned your air filter and checked your spark plug without success, a failing carburetor is often the culprit.

This kit is designed to replace the carburetor unit itself. While it includes the essential components for the carburetor swap, it does not typically include fuel lines, filters, or gaskets unless specified in the package contents, so check your existing fuel system for wear while you have the saw disassembled.
