If you run or ran these to fast the engine would pump oil into the valve cover witch in turn filled the air box and filter.

Even if that were corrected the muffler is still full of oil and takes a while to burn out all of the oil that was sent into it.

Too much gas in the engine oil (starting and stopping, fouling plugs)

Over full of engine oil
