I talked with a production engineer at Kohler today, someone that actually designs and test the latest versions of Kohler engines not a distributor or rep. He told me they were working on a 36 hp carburetored engine for Hustler at this time, I said why not an efi, he said they could get the carburetored engine on line quicker but he thought the 36 efi would probably be in production by 2008. I said if you will put me one together and get it on a Hustler Super Z that will handle it I will be more than glad to put it through it's paces. He then said I might see what we can get worked out on that, he emailed me so if I have any technical questions about the engines we could keep in touch. I really thought that was nice because I hate talking with people about products they don't have full knowledge of and this gentleman can answer any questions I would have about Kohler engines correctly.
