Keihin carb, are my metal parts original?

I started the cleaning process today. This being my first time into a set of keihin cx carbs. I am curious if the jets that are original have this mark on them? It is going to weigh into my choice of re jetting for air pods if they aren't original. Well thanks in advance guys. Also Is it normal for the accelerator pump diaphragm to be rusted on one side? I'm really bummed randakks is out of rebuild kits. Just hear great things about them in the past.
