Since I had a electrical failure of my Kohler generator back in August I thought that my problems would be behind me,but as luck would have it I have either a turbo failure or a exhaust failure of some sort,the gen started to puff some diesel smoke on Thursday,so I ran it as little as possible and by Saturday morning it was leaving soot in the generator bay and was obviously about to totally fail.I was lucky that I was at a race and had my transporter with a 10K Onan that I could plug into,I made it through the weekend but now have to deal with Kohler warranty.
