What oil is recommended by the owners manual? If you used a "cheaper" TCW3 oil and idled for long periods of time, then yes carbon build up is common. Unfortuantely, you had some bad luck. I think Johnson / Evinrude has been making engines for 100 years and only 1 bad comment on this site isn't too bad.
