Have a brand new OS 46 fx I`m preparing to break in. Should I initially start with the needle valve settings as they are right out of the box and richen/lean from there? Seems like I heard that you should turn the high end needle valve all the way in and then back it out about 2 1/2 turns to start with, but don`t know if that`s the right thing to do or not. Thanks for any advice and Merry Christmas to all!
