I dont kow what happened to my rc car?

i was trying to break in the engine, on my hb lighting gt10, and followed the insrtuctions by turning the needle valve to the starting position, i then proceeded to turn the car on, it immediately went crazy, it got up to full throttle, and the wheels were turning like crazy. im not sure if it was something i did to the needle valve, or is there something wrong with my radio?
