Check to see that your muffler is tight on the engine, and the muffler itself is assembled tight.

Like Motorman said. Also is the oil truly black. Look close use a white paper towel and see if it has an Amber color-if so your OK, if not your lean and hot. Try a couple clicks richer and check again. The color should be dark amber but not pure black.

I had the insides get loose in a muffler and it did what You describe.
