Craftsman riding mower smoke and oil on muffler

I have a Craftsmans 917271643 riding mower that emits smoke from the muffler housing immediately after it starts up. There is oil all around muffler hard to tell if its being forced out the exhaust or dripping from somewhere else. Where could the oil be leaking from if not coming through exhaust? What would cause it to come from exhaust? Engine seems to be running fine, just a lot of smoke from oil on the hot muffler...

I re-read and saw oil... at first I thought it said gas for some reason. Ignore my previous reply. Oil on the exhaust is often from a leaking valve cover.
