Default engine break-in and needle settings

I'm planning on breaking in my LRP Spec 3 Truggy. I'm new to the whole 1/8 scale and nitro scene.
In the manual it says that the needle settings should be 3,75 turns. When you give a number for needle settings do you mean turns-in or turns-out? I think you need to tighten the screw and screw it 3,75 turns-out, like the manual says.
But 3,75 turns(-out) seems very rich, right? I know every engine is different and has other settings to run well, but what are the standard needle settings for an .28 engine? And if you want to break the engine in, how many turns out (from the normal settings) do you need to turn the HSN? I think the manual give these rich settings so newbies will automatically run their engines rich..
But thanks

yes it means 3.75 turns out from bottom. You turn the needle all the way in and then back it out. 3.75 is the same 3-3/4 turns out. Do what the manual says and break it in. Yes it is rich but that is the way they all are out of the box. After you break them in you can lean them out.

So 3.75 turns out is the suggested break in setting? It doesn't say that is the break in setting.

Screw the needle all the way in, then screw it back out 3.75 turns. It is supposed to be rich so that the extra fuel will wash out all the debris/particles that may develop during the break-in process and ensure that the motor gets plenty of lubrication.

Id suggest watching some videos on you tube of people breaking in engines so you can hear the right sound of a rich engine. Also helps to know what to expect.
