dristo72,

Ok start by removing the muffler and checking the exhaust port to see if it is blocked up.

If port has excessive amounts of carbon in it clean it out and then start the machine without muffler to see if it peeks out.

Then if all is ok you will then need to check the gauze in the outlet of the exhaust. It also could be blocked up just remove it and clean it as well.

All should be ok if not post again. cheers2
