when you checked the exhaust did you remove the muffler~? I found on my stihl trimmer was doing the samething and carbon had built up in the out port between the motor and the muffler, I made sure the piston was all the way in the up stroke,(to make sure none of that crud fell back into the cyl. head) and scraped out the carbon, then it rev great.
