3 turns sounds about right. When you open it up you dont want too many rpms, mine would bog down so bad it would almost flame. When that happens, crack the fuel tank quicly just to let some air in. its going to suck the fuel out so fast the muffler wont be able to pressurize it fast enough. keep a good eye on your fuel level as it will go through it very quickly. You will also need to keep constant heat on it, so keep a good eye on that. Never let it get below 200...
