Glad you fixed it. Yes, factory settings are always rich, because rich won't hurt your engine. If you will work your LSN just a tiny bump at a time, you will probably notice that at the beginning, the idle only lasts for a few seconds before lowering and then dying. Lean it out a tiny bump at a time until it idles at a steady RPM. Then adjust the HSN, check the idle again, and check the transition last.
