The most common, is running the oil a little too full. There are vents tot he air cleaner, with the idea that excess oil vapor will be recirculated through the motor, but if there's more than a little, it builds up and drips. Tere are other causes, but level too high is the usual culprit. If you do a search for "air cleaner oil drip" you should be able to find a lot of info on this subject.

Reroute that oil somewhere else. That stuff deposits carbon in your heads and combustion chambers and does you no favors. (detonation, change in compression, power loss, etc.)

Yea, your oil level may be high causing it, but I recommed rerouting it away from the carb. There are several ways to do this, homemade or purchased kits.
