QT50 runs 15 seconds then dies

I finally figured out my light spark problem. the spark plug cap was loose from the spark plug wire!! Now it will start and run at high RPM for 10 to 15 seconds or so then die. This happens after it has sat over night. It will not start after it dies. Upon removing the spark plug it is obviious that too much gas is getting to the cylinder. it must be something in the carburator, but I do not know where to start looking. Any Ideas?

Well,Robert,your needle valve may be leaking thru or possibly float is set too high?
