7. Penyelenggaraan

Regular maintenance helps prolong the life of your carburetor and ensures consistent engine performance.

• Kualiti Bahan Api: Sentiasa gunakan bahan api yang segar dan bersih. Bahan api yang basi atau tercemar merupakan punca utama masalah karburetor. Pertimbangkan untuk menggunakan penstabil bahan api, terutamanya semasa penyimpanan.
• Penapis Bahan Api: Replace the fuel filter annually or more frequently if operating in dusty conditions. The included fuel filter should be installed during carburetor replacement.
• Penapis Udara: Pastikan penapis udara anda bersih dan dalam keadaan baik. Penapis udara yang kotor boleh menyekat aliran udara dan menjejaskan prestasi karburetor.
• Storan: Before long-term storage, either run the engine until it runs out of fuel or drain the fuel system to prevent gum and varnish buildup in the carburetor.
