    Default Throttle Adjustment..

    After taking my boat out for the first time i noticed that the throttle was not opening up properly, and couldn't get my small boat moving very fast.
    When back at home, i adjusted the linkages so allow for the carb to open up fully, then realized the carb was remaining partly open on idle, not good.
    How can i adjust the throttle to open up fully, but still allow for normal idle?
    After playing with the linkages my only solution would be to re-shape the cam controlling the carb... not a preferred method.
    My engine is a late 70s 45hp 2stroke 2cylinder (single carb)
    Any help is much appreciated

    Cheers, Aidan

    Ayuh,... Sounds like the control cable is worn internally, not allowing full travel....
    Any Grease is Better,... Than No grease at All....

    Think it has full travel buts its not enough. maybe its not the right controller for the engine. mite just have to file the cam down.. or make a new one up

    There should be no need to start altering the shape of parts on an old motor.-------------Look carefully for the real problems !!-------------It is in gear ( motor stopped )when you are looking for the full throttle on the carburetor??
