I guess my 'eat crow' thread was lost from the server crash. Anyway, the motor's fine; I had to remove the carb and drain water from the float chamber (it came in thru the air intake), and I used some spray carb cleaner. Replaced the plugs also, the fuel was O.K. because the tank floated. The motor started on the 2nd pull, runs good. Thanks to awshucks and metalman for your advice.
