these engines can take some reving so what your problem could now be is either the sparkplug needs to be replaced with a decent NGK brand or you have slight blockage in the carby [ thanks to the stock fuel filter ] go to ;
Carby Cleanout with Pics ] then buy a good fuel filter and use good clean petrol with good quality oil mixed.
