scored an old Sears Craftsman 1400 generator model #580328320 with a Kawasaki engine. At first I thought it was a Tec but on closer inspection, and web search, turns out to be a Kawasaki. Im going to take the generator off of it and clean it up a bit. The engine turns over and has clean oil in it. Is this even worth messing with? anyone have any experience with these? thanks for any help/comments.
