It's sounds like your engine is 4-stroking... (it's a little too rich)

You should run about 4 gallons of gas through your engine before you start trying to tune it, because it will keep changing as it breaks in.
Also, if you're planning on modding your pipe or getting a expansion chamber, you should do that before tuning the carb!
