hopeless d,
Yoy need to do a couple of things:

1. Check exkaust port to see if it has carbon build up.

2. Check muffler screen to see if the mesh is carboned up.

3. Make sure that you are using clean fresh fuel.

Follow these steps first then if you still have a problem, I will give you some other things that will help.
