      Where should the carburetor adjustment screw be on this motor?

        For starting the magneto lever should be
        pointing to around 4 or 5 O’clock as you face
        the motor.
        The mixture lever should point to 3 O’clock
        when the mixture screw is closed. The
        priming lever should be set to push the
        float pin down when the mixture lever points
        to “Prime”. To start open the mixture screw
        so the lever points to “prime”. Watch for
        gas to start dripping. Immediately move the
        mixture screw to about 11 O’clock (a bit more
        than a 1/4 turn from being lightly seated) and
        try to start the motor. Adjust the fuel mixture
        to the best running position. If the motor isn’t
        starting close the mixture screw all the way
        and pull it over 6 or 8 times. If the motor takes
        off and dies it was flooded. Its not uncommon
        to find these motors so worn out they will no
        longer run. Consider yourself lucky if yours
        does.

        A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
