If I let off the gas and then slowly increase the throttle it picks up a few more rpm. Is there a baseline where my needles should be set from the fully closed position? Currently running at sea level, with the LSN at 8 turns out, and the main at 4.25 turns out.
Try richening the HSN 3 hours (that should help). and let us know how it goes.
It sounds lean, judging by the way you explained on how it runs.
