Yeah thanks for the advice. I went ahead and pulled the engine out and checked to make sure the O-ring on the crankcase was good, and the screws were tight. They both were, but I noticed a considerable gap between the muffler and the engine mating point. It looked like there were small washers in between it! So I went ahead and took those out, and I filed the ends down a little to get rid of the carbon build up that was on them and stuck everything back together. And WOW what a difference! The engine is quieter, its not using as much gas, and its not dripping from the engine anymore. Im very pleased with the difference. And I even learned how to hover today! Burned almost half a tank of gas without touching the ground!
