Why not try to figure out when and what type air cleaners and cups were on the 9-2ns?
I think the first air cleaners were made by DONALDSON.I also think the cup was flat bottom and the air tube was the one with the off-set.Don't have much info on how long they were used.I have seen this seen this set-up on 9ns with serial number up to 20xx.My 9n 88xx has the US air cleaner,round bottom cup, and air tube with the vacuum port installed in it near the carb intake.Latest serial number for this was 98xx that I have heard of.Don't have a clue as to when this set-up was discontinued.Any help on this please. don b
