I adjusted mine by first adjusting the throttle stop 1/8 turns, (BTW it took like a tank of gas to adjust it) I would run it, warm it up on that setting, and then pick the truck up and slowly apply the brake, and if it was going to die, I would adjust the stop a little more, run it and do it again, Oh yeah make sure your throttle trim is set up to where you want it, and just do this over and over then eventually you will have it adjusted so when you hit the brake the truck will not die! Then you will be skidding your truck around everywhere, and if yours is like mine it will make the truck screech a little which sounds cool. (I have proline speed hawg IIs which may be why it screeches)
