It's hard to answer your question. I have/had a NS3, a NSR3, a NSR5 and many other engines Nova or otherwise, and I NEVER knew what the stock settings were. Even if I did, it's not very useful as different time of the day, different weather, different track, different humidity, different plug, different pipe would all affect the tuning by as much as 2 turns top and/or bottom. What you need is to ask someone who is experienced at your LHS or local track to teach you and help you tune your engine.
