Z010 003 K021 – Gasket & Diaphragm Kit for STIHL MS 201 TC-M (Genuine ZAMA OEM Repair Kit)
The ZAMA Z010 003 K021 Gasket & Diaphragm Kit is a genuine OEM carburetor repair kit designed to restore the performance of the ZAMA C1Q-S274 carburetor used on the STIHL MS 201 TC-M professional top-handle chainsaw. This service kit includes the essential gaskets and diaphragms required to rebuild the carburetor, helping restore proper fuel metering, improve throttle response, and ensure dependable engine performance.
Over time, carburetor diaphragms can become stiff, brittle, or damaged due to age, ethanol-blended fuels, and regular use. Replacing these wear components with the genuine ZAMA Z010 003 K021 Kit helps eliminate hard starting, poor idling, hesitation, and inconsistent engine operation while extending the service life of your carburetor.

Function
The diaphragms and gaskets inside a carburetor regulate fuel delivery and maintain proper pressure within the fuel circuits. As these components age, they lose flexibility, resulting in poor fuel metering and reduced engine performance.
Installing the ZAMA Z010 003 K021 Repair Kit restores the carburetor's ability to deliver the correct fuel mixture, helping maintain smooth idle, quick acceleration, reliable starting, and consistent power output.
