Advanced EFI & Starting Features
- Battery-Less EFI: The Electronic Fuel Injection system provides precise fuel delivery for easy starts, smooth idling, and superior fuel economy. Because it is battery-less, the EFI is powered by the first few inches of your manual pull-start.
- Manual Rope Start with Auto-Decompression: An automatic mechanical device reduces cylinder pressure during the pull, allowing you to start this 20 HP engine with remarkably little effort—usually on the first pull.
- PrimeStart™: An “auto-choke” system that monitors engine temperature to ensure a reliable start in cold or hot weather without the need for manual adjustment.
