Hi My name isXXXXX will help you wit your question.
The first thing to to check is your clutch adjustment. Do you have any free travel or is the pedal all the way to the top? You should have at least 3/4" of free travel. If your clutch is ok and not slipping. Try changing your fuel filters if your engine is hesitating. I hope this helps. Let me know if you need any further assistance.
