try not to worry about needle settings, especially since you cannnot remember what the factory settings are.
Instead, tune the engine by sound and running cues (I am assuming your engine is already broken in)

For tuning a gasser, (even a KM engine), wtach this vid. If you tune to the sound and performance cues like on this vid, you will have the correct needle settings for your running conditions. Be sure to listen to the noises of the engine in the vid as the guy explains. It is an excellent intsurctional vid.
