More the likley the motor was laid on it's improperly, causing oil to come out of the exhuast. Or the motor was over filled will oil, causing the excess to come out of the muffler.
Clean off all the excess oil. Check your oil lvl and fill or drain if needed. Then hook up to hose and run the motor. It may smoke for awhile, but should reduce in volume slowly over time. Shouldn't take longer then 5-8 min. Once it stops smoking, turn off. Let it stay upright overnight and see in the morning if it is still leaking. If not then no worries. If it is, the you have a leak somewhere.
