Okay, it took me a lot of time but it's almost done! Took it for a test ride today and noticed a problem with the freewheel/RD. The RD is a Campangolo NR pat. 80, which I bought used and completely overhauled. I've read a lot about Campagnolo derailleurs shifting flaws but despite evrything decided to go for it. Basically, it shiftes fine but the chain doesn't run smoothly on the 3rd and 4th sprockets, and on the 2nd one under load. The chain is new and it does run smoothly on the smallest and largest sprockets. The freewheel I am using is a used Suntour Perfect 5sp. I suspect that most likely the freewheel is the cause of the problem although it doesn't look worn. Will report, once I have tried a different freewheel.
Sorry for a crap picture. Still have to wrap the bars.
Is this Suntour Perfect not that perfect anymore?
