I missed this thread the first time it went past (I was probably out in my workshop

Consider how much effort you've already put into sorting out the kickstand spring. That's like a five minute job for an experienced Vespa wrencher, but you're now on Day Three just of that little task--for all the right reasons, like wanting to understand how it works and do it right, but three days nonetheless.
By way of comparison, I'm some kind of freak of nature who does full teardown projects in 3-4 months.
So if we take 3 days, divide by five minutes...carry the one...and you're looking at seriously like two orders of magnitude difference between you and me. 300 months is a lot of years to finish it; basically asymptotic at "never."
And while, sure, next time that might be a five minute task for you next time, there's going to be a thousand more such tasks along the way. You want to have as many of those lessons learned as possible before you take on a teardown.
Even then, it shouldn't be on on your only bike. Riding is the best motivation there is to keep going on a teardown project, because there will be blood, sweat, tears, profanity, side-eye from the wife, hiding SIP and Scooter Mercato boxes, parts in the dishwasher and clothes dryer, the Marge Simpson "mrmmmmmmm" from the wife, lost shipments, Bitte Erzahlung freigeben emails when SIP underestimates shipping, learning about and buying or making specialist tools, backorders, and the list goes on and on.
Most full teardown threads on here run to the tens of pages. Orwell's P200 thread is currently on Page 51 and he's just getting through paint. SDJohn did one that ran to like 80 pages and he never did get it running to his satisfaction. Mine are usually in the teens to twenties.
Have I made my point yet?

And lastly, welcome to NSM! As you've already seen, we're all helpful to a fault, overly verbose, highly opinionated, and always happy to see a new face discover how much fun these old scooters are.
