Hey M4gik, Sorry about the delay in response time. I have been very busy. On full throttle, your carb should only be as open as the throat of the carb, in other words when you look down the carb and fully pull the trigger(the truck power switch should be on but the engine off) the slider should only clear the opening, no further. if it does go further then adjust your EPA on the transmitter so that it does not open any further. Be very sure when you let off of the trigger the carb slides fully closed. If you think pictures will help, I can post a couple for you..



Good Luck and Most of All Have Fun!!
