I have a 90hp Mercury outboard. It is a 2 cycle motor and it is only one season old. The problem I am having is the idle. It idles fine then all the sudden it will sputter out. Its so annoying to start it over and over. I had it out tonight and idled fine just out of the ramp, but when I turned the motor on later that evening it didnt idle well at all. Again I have no problems starting the motor, and it runs great at quarter speed, half speed, and full open. Any suggestions would be appreciated. Thanks for the help
