Installation Guide

1. Safety First: Before starting, ensure the engine is off and cool. Disconnect the negative battery terminal and shut off the fuel supply valve.
2. Access the Carburetor: Remove the engine's upper cowling or cover to expose the carburetor.
3. Document Connections: Take a photo or make notes of how the fuel lines, throttle linkage, and choke linkage are connected to the old carburetor.
4. Disconnect Lines: Carefully disconnect the fuel inlet and any vapor return lines. Be prepared for minor fuel spillage; have a rag ready.
5. Disconnect Linkages: Detach the throttle and choke control cables or rods from the carburetor assembly.
6. Remove Old Carburetor: Unscrew the mounting bolts or nuts holding the carburetor to the intake manifold. Gently remove the unit and the old gasket.
7. Clean Mounting Surface: Thoroughly clean the intake manifold's mounting surface to remove any old gasket material or debris. A clean surface is crucial for a proper seal.
8. Install New Carburetor: Position the new gasket and install the new carburetor assembly. Hand-tighten the mounting bolts initially.
9. Torque Bolts: Tighten the mounting bolts evenly in a crossing pattern to the manufacturer’s recommended torque specification to prevent air leaks.
10. Reconnect Linkages and Lines: Re-attach the throttle and choke linkages, followed by the fuel lines, ensuring all connections are secure.
11. Final Checks: Turn the fuel supply back on and check for any leaks around the carburetor and fuel lines. Reconnect the battery.
12. Test Operation: Start the engine in a well-ventilated area with a proper water supply and check for smooth idling and throttle response. Adjust idle speed if necessary per the engine's service manual.
