Hi, my name is***** will be assisting you.

The first thing that I would look at is the spark plug, then I would move to the exhaust system. I have seen the exhaust system on these machines become partially block or stopped up and it will cause the engine to do this. It creates too much of a back pressure in the system and will cause the engine to perform poorly.
