    We need more information. What engine? 2 or 4 stroke? What carburetor?
    Always supply some basic information when posting questions. It helps us help you.

    the first picture is labeled, the second isn't.
    the idle adjust in the second picture is the screw with the spring on it pointing directly into the camera in the picture, let it out some to reduce your idle speed.

    Wait a minute...........if the idle mixture screw has fallen out, then that's not likely to be the cause of your over-idling.

    For that, the next possibility that comes to mind is your carburetor throttle slide. You'll get a racing engine if that's not installed properly.

    The slide has a slot running along one side. This slot must be lined up with a little 'nub' on the inside of the barrel.

    You need a need a new carp set screw but if your idle is too high even without one it is most likely your throttle cable.

    There is an adjustment at each end.
    The object is to get the outer sheath just the right length so the inner cable itself can go far enough to let the barrel go completely down to the idle set screw stop, but not be so loose it can come off it's stops and not let you get full throttle.

    You need a replacement screw though as you will never be able to set idle with cable alone, it changes every time you turn your handlebars.

    if it isnt a cable issue as KC described it may very well be an air leak, air leaks are bad, causes lean condition that will kill the engine if run very much.

    if the idle screw fell out it was likely do to you having it out so far the spri g had no tension or very little tension on it, so i agree you eitherneed to make sure throttle cable is adjusted with enough slack so the carb slide can move farther down in carb, or you havean air leak between carb and manifold or between intake and cylinder.
