It uses a Walbro or Nikki carburetor <!-- verify: briggsandstratton.com --> and a Champion RC12YC spark plug. Handles the most demanding residential push-mow applications: tall wet grass, slopes, and mulching. Annual maintenance: oil change (SAE 10W-30), air filter, and spark plug. The carburetor main jet and float are the primary service items.
