Installation Guide

Professional installation is recommended. Always consult your engine’s service manual for detailed instructions and torque specifications. The following is a general guide:

1. Safety First: Disconnect the battery and ensure the engine is cool. Work in a well-ventilated area and have a fire extinguisher nearby.
2. Fuel Line Disconnection: Relieve any pressure in the fuel system. Carefully disconnect the fuel inlet line from the carburetor, using a rag to catch any spillage.
3. Linkage and Hose Removal: Disconnect the throttle and choke linkages. Take photos or label any vacuum and fuel hoses to ensure correct reassembly.
4. Carburetor Removal: Unbolt the carburetor from the intake manifold and remove it from the engine.
5. Disassembly: On a clean workbench, carefully disassemble the carburetor. Pay close attention to the order and orientation of all small parts, including jets, screws, and springs.
6. Cleaning: Clean all non-rubber components with a quality carburetor cleaner. Ensure all passages are free of debris. Do not use wire to clean jets, as this can alter their calibrated size.
7. Component Replacement: Replace the old gaskets, seals, needle, and seat with the new parts from the kit. Ensure the new O-rings are properly seated.
8. Float Adjustment: Install the new float components and adjust the float height according to your service manual'''s specifications. This step is critical for preventing leaks and ensuring proper fuel supply.
9. Reassembly & Reinstallation: Reassemble the carburetor and mount it back onto the engine. Reconnect all linkages, hoses, and fuel lines.
10. Final Checks: Reconnect the battery, prime the fuel system, and carefully check for any fuel leaks before starting the engine. Start the engine and adjust idle speed and mixture screws as necessary for smooth operation.
