John Deere 757 Kohler replace the Kawasaki. The Kohler engine come with clear instructions and kit. Just mark the wire on the mower as you take them off. The only extra work is simple it to remove the short shaft off the old motor and put it on new. Kohler is just as good as the Kawasaki engine except if ever needed to work on it way easier to get support and help and cheaper then John Deere. I strongly suggest you do the Kohler swap
