I have 2 sets of carbs here , they both have the N-8 one reads 625 (has the 5ct7 needle) other carb emul's read 638 (this set had 5ct9's and 7's) the 625 has the larger hole. I'm trying to match one set from these 2 , but so far the spare set reads good compared to the set that was on the bike where jet sizes are concerned. from the jets I am able to read so far anyway.
