What maintenance will keep the carburetor working season after season?

Routine care prevents fuel-related issues and extends service life: use fresh gasoline, add a fuel stabilizer for storage, and avoid letting fuel sit in the bowl for long periods. Periodic inspection and cleaning of the air filter, fuel filter, and choke components keeps performance consistent.

• Use clean, stabilized fuel and change filters annually
• Inspect for leaks, cracked hoses, and loose fasteners
• Clean throttle shaft and jets if symptoms reappear
• Store mower with dry fuel or stabilized fuel for winter
