So i just got a Firestorm 10T truck and i started trying to tune the engine because it always stalled, i adjusted the idling needl, and it stopped stalling. Came another problem, it engages the clutch, even without any throttle, so can only be stopped if i pull the brakes and don't let it go. Can somebody help me, how to adjust everything so it doesn't stall but stays still when off throttle?
