2. Remove Carburetor: Carefully detach the throttle linkage and fuel hoses, then unbolt and remove the carburetor from the engine manifold.
3. Disassemble: Place the carburetor on a clean, organized surface. Disassemble it piece by piece, taking photos as you go to remember the order of assembly.
4. Clean Components: Thoroughly clean all non-rubber metal parts with a quality carburetor cleaner spray. Ensure all small passages and jets are clear of debris. Do not use cleaner on rubber or plastic parts.
5. Install New Parts: Carefully replace the old gaskets, O-rings, seals, needle valve, and float with the new components from the kit.
6. Reassemble Carburetor: Reassemble the carburetor in the reverse order of disassembly. Make sure the float height is set to the manufacturer's specification.
7. Reinstall and Reconnect: Mount the reassembled carburetor back onto the engine. Reconnect throttle linkages and fuel lines securely.
8. Final Adjustments: Reconnect the battery. Start the engine and allow it to warm up. Adjust the idle speed and air/fuel mixture screws according to your engine’s service manual for optimal performance.
