that's a difficult one to tell, it all depends on how accurate your LSN was when you started moving your HSN. If your idle gap is good, then you just adjust the LSN so that the idle gain is stable. if the idle gap is off, you will have to work both LSN and idle screw. You can do a rough temp test on your LSN. Rev the engine and let it fall back into idle, then temp it continously. Temp should not go higher (this would mean a lean LSN) and not drop too much (whould mean rich LSN).
