5. Operating Instructions

After successful installation, follow your generator's specific operating instructions. The carburetor's primary function is to mix air and fuel for combustion. A properly installed carburetor should allow your generator to start and run smoothly.

• Ensure the fuel tank is filled with fresh, clean fuel.
• Open the fuel valve.
• Set the choke lever according to your generator's starting procedure (usually full choke for cold starts).
• Start the generator using the pull cord or electric start.
• Once the engine starts, gradually move the choke lever to the 'run' position as the engine warms up.

6. Maintenance

Regular maintenance of your carburetor and generator components will extend their lifespan and ensure reliable performance.

6.1 Fuel System Care

• Use fresh, clean, unleaded gasoline. Stale fuel can cause carburetor issues.
• Consider using a fuel stabilizer if the generator will be stored for extended periods.
• Regularly inspect and replace the fuel filter to prevent contaminants from reaching the carburetor.
• Drain the fuel system if storing the generator for more than 30 days.

6.2 Air Filter Maintenance

• Clean or replace the air filter regularly as per your generator's manual. A dirty air filter can restrict airflow and affect carburetor performance.
