Over full, milky and runny sounds like you are getting fuel contamination to be over full and runny. Milky oil is a sign of a water intrusion. Hope its only condensation from the cool temps. I am guessing that the needle in the carb stuck temporarily allowing fuel to run in the motor. Change the oil and filter and watch it.
The world will not be destroyed by those who do evil, but by those who watch them without doing anything. Remember what He has done and remember that He is not done yet!-- GOD IS GOOD
