I knew a 621 thread would draw you out Niko!!!! A good percentage of what I have learned about these saws I learned from our discussions over the years.....generally by being patiently shown the error of my thinking and/or opinions!! LOL!!
Sweet...that would be great...don't think I've seen one before.Jonsered supplied a special tool with the 621 (and other saws as well but I haven't owned any of those) to aid in clutch removal. A simple metal plate that hooks through one of two slots on the clutch drum and under the crankcase of the saw to lock it in place when removing and installing the nut. I lost mine for a while, and when it reappeared in my tool box I proceeded to make a copy.
If I have time and remember it, I will take some photos of the original and my copy.

Somewhat similar but actually closer to the 80 or perhaps I should say the 80 is more like the 621. But of the Jonsereds that are like different models the 621 stands rather alone. It has a totally different trigger handle/AV assembly than all the others, which is a holdover from it's ancestors the 60/601. Then it became the 62 which is indistinguishable from the 621. The 111S is that way too, being a very different way of doing things/design than all the others. As Mark said, the 621 was way ahead of the curve in the chainsaw world when it came on the market.
There surely were a few differences between most 62s and most 621 - but I don't think anyone knows which differences appeared exactly when the designation changed. Then we usually don't know what has been changed later on (most) saws that old - so some 62s no doubt look like 621s today. The serial number surely will help.
The change from 3 to 4 rows of holes in the "silver" colored screen on the recoil cover did not happen at that exact time, but a bit into 621 production - but I don't know if the color change and clutch side attachment of the handlebar did.
Until proven wrong, I believe the change of the handlebar attachment was the main reason for the designation change....
I was unaware of the handle bar attachment change......I have a 62 shop manual at the shop.....I will look into this and see if I can gain any more info. This saw is a later production model...

What method did you use to clean the parts before reassembly? They are perfectly clean but not oily at all suggesting something other than a parts washer.
BTW, best build thread I have seen in a long time!

Keep it going Robin , really enjoy your build/rebuild threads ! That goes for anything you build or rebuild !! Master craftsman that you are !
We all know it will be perfect as always ! LOLIt's not running yet John.......it may keep going long after I wish it would stop!!!
