Noel, I may need to use your write-up in my PhD dissertation on FSU lens CLA 
I am starting to appreciate more the skills required to adjust photo gear, I certainly don't have much of those.
Anyway, by now I am pretty certain that the reason my J12 has a tight spot is because of a machining error of some kind, i.e. one or two of the wide "keys" on the lens shaft are just a tad outside of the tolerances for the mount (I assume the mount is OK as it works well with all the other lenses).
I use the two Kievs now with either the Helios lens or (more so) with the 135 Nikkor, which is amazing. As a matter of fact the 135mm Nikkor is the reason I have not yet sold my Kiev outfit - if I take the time to focus properly, to my eyes it produces images nearly as good as my 77mm Pentax limited, which is the best lens I have.
But, now that I (again) have more photo gear than I need, the Kievs and FSU lenses will probably have to go. Of course, everyone already has a Kiev!-))

It seems that newer lenses on older bodies, or vice-versa, don't work very well.
When I bought my '56 IIIa, the seller proposed me to mount a 80s Helios 103 on it and it didn't work, unlike the '57 Jupiter 8. It may be the pb you're encountering with your 4AM?

Stéphane, that's probably right. The NOS Helios I got from fedka will only mount on one of the Kievs, while the old Helios works on both.
I guess you get what you pay for, i.e. all the roads lead to Leica..?
