Honda BF 40
The uniquely compact, durable design of the BF 40 keeps it running smooth and powerful year after year. And just like fuel injection, the Autostart enrichment automatically adjusts the air-fuel mixture for quick, easy starts and warm up. A fuel-efficient 3-to-3 induction feature saves space and weight.
