I am not calling you wrong
I'm just letting you know what I found. I bought them from Oregon Fuel Injection a few years back. They have been scribed with "OFI 8/10" for the month I bought them. I'm wondering if they switched out the nozzle? (I called, they did not swap/upgrade parts) They were supposed to be NIB (and they were). The nozzle part number is Delphi 6801169 KCM, for what its worth.
I also wanted to add that the spring I found in my G code was noticeably longer than the B code spring. In your video, it shows the opposite. What I did notice is that the difference in length was made up in shims (a lot of them). Again, not calling you wrong here, I'm just trying to wrap my head around what I have in the shop.
