Answer
It sounds to me like you have either a rich running condition or a fuel leak??  Have a look around to see if you can locate any external fuel leaks.  To determine if you have a rich running condition, remove a spark plug or two and see if they are dark black or smell of fuel, also check for black smoke or dark exhaust. They are also signs of a rich condition.
Hope this helps.
