    I have a 89 40 hp evinrude, that won't run at high speed. It been that
    way whenwe started it up this year. It was fogged for the winter. I
    have rebuilt the carbs, new fuel filter, plugs. Tried new gas. It start
    up fine. When you start it up cold, we'll pull up the handle to give it
    more air. And it use to scream. Now it just run realy ruff. I been told
    it was the carbs. They were very clean inside, replaced the guts. Blow
    out all the holes.
    Not sure what to check now!

  2. need to use carb cleaner blow out jets
    other than that replace plugs

    Does it have a primer bulb in the fuel line? If so, that sounds like symptoms of it being dry rotted.
