Cuts off at full throttle

[HPIsavagexl]

Hi
Just a week ago i was riding my hpi savage xl k5.9 and it runned perfect, 2 days later i wanted to ride again but the roto start blocked all the time... so i fixed that but now if i give full throttle the engine goes out.
Any help fixing this???

There are a lot smarter and more experienced people on this forum, but the first thing I'd check is your HSN (High Speed Needle).
