Well, I was looking over an O.S. carb today and I see they Too are Long LSN carbs. Atleast the 2 I have are. So they should tune the same as a Go Long LSN carb or vice-versa correct? Just something that made me go hmmm..
I don't think it has anything to do with the length of the needle. Long needles just tend to run a bit leaner at half throttle situations. OS and Nova carbs tune very similar despite Nova's having a short needle.
