Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is cool. Work in a well-ventilated area and have a fire extinguisher nearby.
2. Remove the Carburetor: Disconnect the fuel line, throttle linkage, and any other connections. Remove the mounting bolts and carefully take the carburetor off the engine.
3. Disassemble: Place the carburetor on a clean workbench. Carefully disassemble it, taking note of the location of each screw, gasket, and component.
4. Clean Components: Thoroughly clean all metal parts with a quality carburetor cleaner. Do not use cleaner on rubber or plastic parts. Ensure all passages and jets are clear of debris.
5. Install New Parts: Carefully replace the old gaskets, seals, needle valve, and float with the new components from the kit. Ensure the float is set to the correct height per your engine's service manual.
6. Reassemble: Reassemble the carburetor in the reverse order of disassembly. Do not overtighten screws.
7. Reinstall and Test: Mount the carburetor back onto the engine, reconnecting all lines and linkages. Start the engine and check for leaks, adjusting the idle and mixture screws as needed.
