Fair point! That is why at the start of the last S1 season I made up sets of jets for our entire awning (10 sets)wich were all matched with each other so this problem would not arise.
I cannot confirm that everyone maintained their sets complete, however as I held my own referance set I could replace any missing jet within the 10 sets with another of the same size as their missing one.
As I said in a previous post, it does not matter that much what your jets actually say on them as long as long as they are linear in the steps between and you have based your data on this set.
With regard to the primary jets I have not measured these.
As for the main jets I am yet to find any that are the size stamped on them, and believe me I have measured hundreds!
