What you are describing could be one of the following; too much oil in the crankcase, fuel in the crankcase, or if the unit was tilted more than 15 degrees. Please check the oil level and make sure it is not thin and does not smell like fuel.
We would recommend taking the unit to an authorized service center for repairs to the unit. You can locate a service center here: http://bit.ly/14yWuSi
