Installation Guide
- Safety First: Ensure the engine is off and cool. Disconnect the battery and work in a well-ventilated area.
- Disconnect Fuel Lines: Carefully disconnect the fuel inlet and any other attached lines from the old carburetor. Have a rag ready to catch any spilled fuel.
- Remove Old Carburetor: Loosen and remove the mounting bolts or nuts securing the carburetor to the intake manifold. Detach any throttle or choke linkages.
- Install New Carburetor: Mount the new carburetor onto the manifold, ensuring any gaskets are properly aligned. Secure it with the original bolts/nuts.
- Reconnect Linkages & Lines: Reattach the throttle and choke linkages. Reconnect the fuel lines securely.
- Final Checks: Prime the fuel system and check carefully for any leaks around the carburetor and fuel lines before starting the engine.
