    Not likely you're to rich. When you go to shut it off what is the engine idling at? Any thing over about 850 rpm will cause the enigne to run on after you shut off the ignition. This is the most common cause for this problem. It may also indicate if your idle is going a little higher after it's warmed up you may be just a bit to lean. Try and close the throttle blades just a bit with a quarter to half turn out on the idle speed screw and see if this helps.

    If the timing is too far advanced it will tend to diesel when you shut it off too...
