I have pretty much decided on a Gravely 148. The choice in engines is the Kawa 22 hp or the 23 hp Kohler EFI. The Kohler cost about $500 more. I've had good luck with both Kohler and Kawa v-twins. Never had a EFI before. The EFI is supposed to save about 25% in fuel. That makes me interested in the Kohler. Anybody have experience with the Kohler EFI's. Anybody here that could tell me any information? I would appreciate it.
