Installation Guide

1. Safety First: Disconnect the boat's battery and ensure the engine is cool. Work in a well-ventilated area and have a fire extinguisher nearby.
2. Access the Carburetor: Remove the engine cover and flame arrestor to access the carburetor.
3. Disconnect Lines: Carefully disconnect the fuel lines, throttle linkage, and any vacuum hoses connected to the carburetor. Label them to simplify reassembly.
4. Remove Carburetor: Unscrew the mounting nuts or bolts holding the carburetor to the intake manifold and carefully lift it off.
5. Disassemble: Place the carburetor on a clean workbench. Disassemble it piece by piece, laying out the parts in order on a clean cloth. Take photos as you go for reference.
6. Clean Components: 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.
7. Install New Parts: Carefully replace the old gaskets, seals, needle, diaphragms, and o-rings with the new components from the kit. Ensure each part is seated correctly.
8. Reassemble Carburetor: Reassemble the carburetor in the reverse order of disassembly, making sure all screws are tightened to the proper torque.
9. Reinstall and Reconnect: Mount the rebuilt carburetor back onto the intake manifold, reconnect all linkages and hoses, and install the flame arrestor.
10. Test and Adjust: Reconnect the battery, start the engine, and check for fuel leaks. You may need to adjust the idle speed and mixture screws for smooth operation.
