4. Installation / Setup
This section outlines the general steps for installing the repair kit components. Specific carburetor models may have slight variations. Refer to your engine's service manual for detailed instructions if available.
4.1 Disassembly
- Carefully remove the carburetor from the engine.
- Clean the exterior of the carburetor to prevent dirt from entering internal passages.
