6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your carburetor.

• Fuel Quality: Always use fresh, clean fuel. Stale or contaminated fuel is a primary cause of carburetor issues. Consider using a fuel stabilizer if the engine will be stored for extended periods.
• Fuel Filter: Regularly check and replace the fuel filter (if equipped on your engine) to prevent debris from entering the carburetor.
• Air Filter: Ensure the air filter is clean and properly installed. A dirty air filter can cause the engine to run rich and affect carburetor performance.
• Cleaning: If the carburetor becomes clogged, it may require cleaning. This typically involves disassembling the carburetor and cleaning jets and passages with carburetor cleaner. Consult a professional if unsure.
