    Here is something that got me thinking. I have a 66″ Evinrude and a 1954 neptune, The carbs have throttle plates (Butterflies) I Really never paid attention till last night, my 41″ Neptune, the Carb does not have a throttle plate on it.. How exactly then does it regulate the speed then?? Does it adjust the timing instead?

    Yep – Carb is wide open all the time. Speed
    is controlled by advancing or retarding the
    timing. Common arrangement in the early
    motors.

    You're only as smart as the person you're talking to.
