I dont wanna sound like i'm Slow but i've never heard an LSN. By that you do mean the low end needle the high end needle and the idle screw right? anyway i think all my settings are correct because i've taken it down to a hobby store and they tuned it correctly for me.(that was when it was running correctly, and i haven't messed with the settings since. So if the bearings are just messed up then that could be the problem. What about the spring i told you guys about. Does that have anything to do with it. Oh and what do you mean by the drag. I've been in the sport for about 1 year and havent had any problems with it so just refresh my memory.
