Its the ignition system thats the problem. If the engine is the Zenoah copy with 2 coils then you can change both coils for genuine Zenoah ones and gain several thousand rpm. If its the engine with a single coil then not much you can do as far as I know.

I can just see one coil..and something ignitionthing in the front..

Hi rabardio

How does yours compare to this one on youtube?

Looks like he just installed a zenoah in it instead of the stock china engine

Yours has the 2 coils. Change them for Zenoah coils and its running good after that.
