Boggy 2-cycle? Try this  

your 2-cycle OPE (Outdoor Power Equipment) might stumble or lose revs (bog down) because of a simple air leak at the carburetor. Pop off the airbox cover and check the tightness of your bolts that secure the carburetor - they may have loosened up like mine did after a month of solid use on this Echo PB-2520. Cheers!
