Just got my firestorm about a week ago and have been going through the tuning precedures just like it says in the book. But I have noticed whenever I slow down rapidly or slow down at all for that matter, the engine will cut off. The engine will run when no throttle or break is applied and seems to be running good, but as soon as i slow down enough to turn or stop the engine will cut off. I do not even know where to start due to the fact that this is my first one.

Thanks guys
