Thank you John,
I'll start by looking into the parts in the outer transmission cover. I seem to remember checking the plungers and thinking "they look just about new". They might just as well be new but wrong from previous owner. I bought the bike in baskets from a person who in turn bought it in baskets and quite quickly gave up on re-building. Realizeing he was in over his head.
As was I by the way -I just didn't give up...
