Sounds like a fuel problem. Did you replace the fuel filter ????
Slip the muffler off and check for a clogged exhaust port.
People have a bad habbit of running on too rich oil mixes or using cheap oil that is not ashless so coke builds up on the exhaust port & blocks it.
Running the engine under stressful loads that cause the engine to run slower than it should will also block the exhaust port .
