Thank you so much for taking the time to check out your Spirax. Wow. I
think my problem is that the return spring is missing. The rod is
visible, with it's helical slot, as the pulley and body move toward the
spokes. I am assuming it should look like the flat spring in a pull
chain type.
I should have guessed that there was some thing wrong with the derailleur, like a weak return spring, or the previous owner would not have replaced it with a Suntour! This bike was used a lot and looks it.
It appears that the bike will be a bit non-functional for the show. I'll be scrounging around for a proper replacement RD at the swap tables.
Thanks again,
