Default JP Needle settings

I have a JP Black C12 engine. I am just wondering what sort of needle settings (ballpark) other people are running. I also have a Novarossi CX12 and the needle settings are totally different to the JP C12 settings. I am running 2 3/4 out on the high end and 3 3/4 in from flush on low end on the JP. These settings seem to be wierd to me but they seem to work. Any thoughts?

you cannot compair engine to engine needle setting without consider what kind of pipe that you use with them. different pipe has different back pressure and that make the high difference on the needle setting especially on the main needle.
