5. Operating Instructions

After successful installation of the FOLIAGE carburetor, follow these steps to operate your lawn mower:

1. Refill Fuel Tank: Fill the lawn mower's fuel tank with fresh, appropriate gasoline.
2. Starting Procedure: Follow your lawn mower's manufacturer instructions for starting. This typically involves setting the choke, priming the engine (if your model has a primer bulb), and pulling the starter cord.
3. Warm-up: Allow the engine to run for a few minutes to warm up before engaging the blades or beginning mowing.
4. Performance Check: Listen for smooth engine operation. If the engine runs rough or stalls, refer to the Troubleshooting section.

6. Maintenance

Regular maintenance of your carburetor and associated components will ensure optimal performance and longevity:

• Air Filter: Periodically inspect the air filter for dirt and debris. Clean or replace the air filter as needed, especially in dusty conditions. A clogged air filter can restrict airflow and affect carburetor performance.
• Fuel Filter: Inspect the red fuel filter for blockages or contamination. Replace the fuel filter annually or if it appears clogged or dirty.
• Fuel Lines: Check fuel lines for cracks, leaks, or hardening. Replace any damaged fuel lines immediately.
• Fuel Quality: Always use fresh, clean gasoline. Stale or contaminated fuel can cause carburetor issues.
• Storage: For extended storage (over 30 days), it is recommended to drain the fuel system or use a high-quality fuel stabilizer to prevent gum and varnish buildup in the carburetor.
