Yes, seeking a chrono is on my list but not a priority.

The output was poor - probably because the spring was somewhat compressed after 45+ years - but now seems closer to where it should be, ie closer to 10ft/lbs, as a result of the action taken.

The mechanics of what are fairly simple alterations fascinate me, so I thought I would request the views of the technical people, here, who know about such things. That said, I would never contemplate complex alterations, such as playing around with the transfer port; the technical aspects of that are sufficient for a Phd!
