Configurazione e installazione
La sicurezza prima di tutto: Before beginning any installation, ensure the engine is turned off, cool, and disconnected from its power source (e.g., spark plug wire removed). Wear appropriate personal protective equipment, including gloves and eye protection.
- Preparazione: Gather necessary tools such as wrenches, screwdrivers, and a clean rag. Have a container ready to catch any spilled fuel.
- Rimuovere il vecchio carburatore:
- Individua il carburatore presente sul tuo motore.
- Carefully disconnect the fuel line, throttle linkage, and choke linkage from the old carburetor. Be mindful of any clips or springs.
- Unbolt the old carburetor from the engine manifold. Note the position of any gaskets.
- Rimuovere il vecchio carburatore e le eventuali vecchie guarnizioni.
- Installare il nuovo carburatore:
- Ensure the mounting surface on the engine is clean and free of debris.
- Place the new mounting gasket (included in the package) onto the engine manifold.
- Position the new Anfu carburetor onto the gasket and align the mounting holes.
- Secure the carburetor with the original bolts, tightening them evenly to prevent air leaks.
- Reconnect the throttle linkage, choke linkage, and fuel line to the new carburetor. Ensure all connections are secure and move freely.
- Install the new fuel filter and fuel valve in the fuel line as appropriate, ensuring proper flow direction. Use the provided metal rings to secure the fuel line connections.
- If applicable, install the new primer bulb.
- Rifornimento iniziale: After installation, refill the fuel tank with the appropriate fuel type for your engine. Prime the carburetor if it has a primer bulb, or allow the fuel system to naturally fill.
- Controllare eventuali perdite: Before starting the engine, visually inspect all fuel line connections for any signs of leaks.

Istruzioni per l'uso
Once the carburetor is installed, the engine should be ready for operation. The carburetor is pre-set for general use, but minor adjustments may be necessary for optimal performance depending on your specific engine and environmental conditions.
- Avviare il motore: Follow your engine manufacturer's specific starting procedures. This typically involves engaging the choke (if present), priming the carburetor (if equipped with a primer bulb), and pulling the recoil starter or engaging the electric starter.
- Funzionamento dello starter: The choke enriches the fuel mixture for cold starts. Once the engine starts and warms up, gradually disengage the choke.
- Controllo dell'acceleratore: Use the throttle lever to control engine speed.
- Regolazione del minimo: If the engine idles too fast or too slow, or stalls at idle, the idle speed screw on the carburetor may need minor adjustment. Turn clockwise to increase idle speed, counter-clockwise to decrease.
- Mixture Adjustment (if applicable): Some carburetors may have adjustable high-speed and low-speed mixture screws. Refer to your engine's service manual for specific adjustment procedures. Incorrect adjustments can lead to poor performance or engine damage.

Manutenzione
Regular maintenance of your carburetor and fuel system is essential for long-term performance and reliability.
- Qualità del carburante: Utilizzare sempre carburante fresco e pulito. Il carburante stantio o contaminato è una delle cause principali dei problemi al carburatore. Si consiglia di utilizzare uno stabilizzatore per carburante, soprattutto durante lo stoccaggio.
- Filtro del carburante: Regularly inspect and replace the fuel filter (included in this kit) to prevent debris from entering the carburetor.
- Filtro dell'aria: Ensure your engine's air filter is clean and properly installed. A dirty air filter can restrict airflow and cause the engine to run rich.
- Pulizia del carburatore: If the engine experiences rough idling, stalling, or loss of power, the carburetor may need cleaning. This typically involves disassembling the carburetor, cleaning jets and passages with carburetor cleaner, and replacing gaskets if necessary. For complex cleaning, professional service is recommended.
- Magazzinaggio: Before long-term storage, run the engine until it runs out of fuel, or drain the fuel system to prevent fuel degradation and gumming in the carburetor.
