8. Maintenance
Regular maintenance ensures the longevity and optimal performance of your carburetor and engine.
- Fuel Quality: Always use fresh, clean, and appropriate fuel for your engine. Stale or contaminated fuel is a common cause of carburetor issues.

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.
- Storage: Before long-term storage, drain the fuel from the carburetor bowl or use a fuel stabilizer to prevent gumming and varnish buildup.
