I put my Duc away for the winter treated the fuel and ran once a month. Two months ago I tried to run and it ran really rough and I had to keep throttle slightly on to even keep running. Tried again this month and same thing. Brought it up to temp but still running like %!ยค. Could the choke be stuck? Does anyone know where I can get manual for the 2006 sport 1000 on line? Thanks, Jeff.
