Advanced EFI & Starting Features
  • Battery-Less EFI: The Electronic Fuel Injection system provides precise fuel delivery for smooth idling and superior fuel economy. Because it is “battery-less,” the EFI is powered by the first few inches of your manual pull, ensuring a reliable start without needing a heavy battery.
  • Manual Rope Start with Auto-Decompression: An automatic mechanical device reduces cylinder pressure during the pull. This makes starting the 20 HP engine incredibly easy—often requiring only one hand—even on the first pull of the day.
  • PrimeStart™ Technology: An automatic “auto-choke” feature that monitors engine temperature to ensure a quick start in both freezing and tropical climates without manual adjustment.
