5. Instructions d'utilisation (après installation)

After installing the new carburetor, perform the following checks before starting the engine:

1. Vérification du carburant : Ensure the fuel tank contains the correct fuel/oil mixture as specified by your engine manufacturer. Check for any fuel leaks around the carburetor and fuel lines.
2. Throttle and Choke: Verify that the throttle and choke levers move freely and return to their proper positions.
3. Démarrage initial:
   • Set the choke to the "START" or "CLOSED" position.
   • Prime the carburetor if your engine has a primer bulb, until fuel is visible.
   • Pull the starter cord according to your engine's starting procedure.
   • Once the engine fires or attempts to start, move the choke to the "RUN" or "OPEN" position.
   • Continue pulling the starter cord until the engine runs smoothly.
4. Réglage du ralenti : Allow the engine to warm up for a few minutes. If the idle speed is too high or too low, locate the idle adjustment screw on the carburetor (refer to your engine's manual for exact location) and adjust it until the engine idles smoothly without stalling.
5. Vérification des performances : Test the engine under light load to ensure proper acceleration and power delivery.

6. Entretien

Regular maintenance of your carburetor and associated fuel system components will ensure optimal engine performance and longevity.

• Filtre à air : Regularly inspect and clean or replace the air filter. A clogged air filter can restrict airflow to the carburetor, leading to poor engine performance.
• Filtre à carburant : Check and replace the in-tank fuel filter periodically. A dirty fuel filter can restrict fuel flow and cause carburetor issues.
• Conduites de carburant : Inspect fuel lines for cracks, leaks, or hardening. Replace damaged fuel lines immediately.
• Nettoyage du carburateur : If the engine experiences performance issues due to fuel contamination, the carburetor may need cleaning. This typically involves disassembling the carburetor, cleaning jets and passages with carburetor cleaner, and replacing gaskets. This procedure should only be performed by individuals with mechanical experience.
• Qualité du carburant : Always use fresh, clean fuel mixed with the correct ratio of 2-stroke oil (if applicable to your engine). Stale or contaminated fuel is a common cause of carburetor problems.
