So I checked what happens if I lean the LSN more. The engine sounds after a high speed run like ah ah ah - it stutter.
Your almost there!
Try to lower the idle a little bit, you will see it will work, if you give a short pull on the throttle, you will give the engine a bit extra fuel, which will lower the idle....
So, just lower the idle a little bit....
Only, it might be possible that the idle will be to low when your engine is not fully on operating temps after a warm start... (hard to explain, you will recocnize it when it happens)
