I'm pretty sure you are talking about a nitro truck. If so, you can turn the high end needle out about 1/4 turn and it will slow it down. One thing you need to do is make sure it's tuned right and not too lean. If it's too lean, it will burn it up really fast. You can also adjust your throttle end point to not open the carb up so much.

counter clockwise. It's best to have a temp gun as well and never let the engine go above about 240ºf.
