Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is cool. Shut off the fuel supply and safely disconnect the fuel lines.
2. Remove Airbox and Carburetor: Detach the airbox cover and filter. Loosen the mounting bolts and remove the carburetor from the intake manifold, disconnecting any throttle linkages or hoses.
3. Disassemble Carburetor: Working in a clean area, carefully disassemble the carburetor. Pay close attention to the location of each jet, screw, gasket, and the float assembly.
4. Clean Components: Thoroughly clean all metal parts with a quality carburetor cleaner to remove varnish, dirt, and fuel residue. Do not use cleaner on non-metal parts.
5. Install New Parts: Carefully replace the old gaskets, seals, float needle, and other components with the new parts from the kit. Ensure each part is seated correctly.
6. Reassemble and Reinstall: Reassemble the carburetor, making sure not to overtighten screws. Mount it back onto the engine and re-attach all linkages and fuel lines.
7. Adjust and Test: Reconnect the battery. Start the engine and allow it to warm up. Adjust the idle speed and mixture screws according to your service manual for smooth operation.
