    Default 4 Hp 2 cycled aircooled. Idler settings?

    I was told by a friend mechanic who only gives me advice, to adjust the idler screws on the carb. However I am not sure how many times to turn the screw. I am not getting gas into the cylinder and he said this might be the problem. Also could it be a connection between the carb and the cylinder? hoping to get this running soon with help from my fellow forum runners! (as i call them)
    once again it is a 1968 4 horsepower ted williams, 2 cycle aircooled motor.

    Any information for would very helpful, Thank you!

    That carb is probably not the emissions carb that most of have so I will try and post from the book,

    CARBURETOR ADJUSTMENTS
    IDLE SPEED ADJUSTMENT
    This screw is located on top of the carburetor and
    contacts the throttle. To pre-set the idle speed, back
    out the screw, then turn in until the screw just touches
    the throttle lever. Finally, turn the screw in one (1)
    turn. Once the engine is running and brought up to
    operating temperature (3-5 minutes), the final idle R.P.M.
    can be adjusted with the aid of a tachometer.
    FLOAT TYPE-FIXED MAIN, IDLE ADJUST
    Turn the mixture adjusting screw in (clockwise) finger
    tight, then one (1) turn out (counterclockwise). This
    setting is approximate and will be enough to allow
    the engine to start so that final carburetor adjustments
    can be made. Start the engine and allow it to warmup
    for approximately 5 minutes.
    Do not adjust the
    carburetor with the engine cold.
    NOTE:
    If the engine falters or stops after the choke
    lever is moved to the "OFF" position, open the mixture
    adjusting screw 1/4 turn counterclockwise and restart
    the engine.
    With the engine running, place the speed control in
    the "slow" position. Turn the mixture adjusting screw
    clockwise until the engine starts to falter, remember
    this location. Next turn the screw counterclockwise
    until the engine start to sputter or drops in R.P.M.,
    remember this location. Now turn the screw clockwise
    until it is halfway between these two locations. This

    will be the optimum carburetor setting.

    well after a little digging, i found that this motor indeed is a water cooled, glad i started it in water, however it would seem that the impeller needs replacing, the water has small rubber shavings and pieces in it, im guessing thats the bad impeller?? maybe the seals?
    any ideas where i can get a new impeller? i know they are pretty common, i just dont know where to get one for this year and model.
