Start on the HSN with about 2.5-3 turns out and the LSN about 3 turns out. The low and high end should be a little rich. What you do is to start the engine up (runs fine with a 12x6, 12x8 13x6, 14x4W) and tune her to the maximum revs then ease off by say 3-4 clicks. Now you have to check the low end, let it idle and then throttle up, if it cuts abruptly the low end is to lean, if it gurgles a little and hesistates ... its too rich.

Another way it to let the engine idle and then remove the fuel tubing. If the engine gains RPMs before quitting then its too rich and if it loses RPMs before quitting its too lean.

This will just set the base line for your engine, best is when you fly her. I always check engine head temp when I land, I like to keep my engines to about 230F.
