2. Remove Carburetor: Disconnect the fuel line and throttle linkage. Remove the mounting bolts and carefully detach the carburetor from the engine.
3. Disassembly: Place the carburetor on a clean surface. Carefully disassemble it, taking photos as you go to remember the order and orientation of parts. Pay close attention to small components like jets and springs.
4. Cleaning: Thoroughly clean all metal parts with a quality carburetor cleaner to remove varnish, gum, and dirt. Do not use cleaner on rubber or plastic parts.
5. Install New Parts: Replace the old gaskets, seals, float, and needle valve with the new components from the kit. Ensure each part is seated correctly.
6. Reassembly & Reinstallation: Reassemble the carburetor in the reverse order of disassembly. Mount it back onto the engine, reconnect the throttle linkage and fuel lines.
7. Adjustments: Once installed, start the engine and adjust the idle speed and air/fuel mixture screws according to your engine's service manual for smooth operation.
