Could I get a little help here?mackgoo

I'm getting my cross bike ready for the winter, I know I'm running late. Any way I've completely taken apart my rear derailleur to clean it up, that grit gets everywhere. This is a Campy 10sp.
I have two questions;
1. When re assembling the jockey wheel cage to the body how many times should I spin the cage around for the propper spring tension? I can spin it around at the most twice. Is there a benefit to having a heavy spring tension? Or conversley is there a benefit to having a lite spring tension?
2. When re assembling the portion that makes up the bolt that secures the derailleur to the frame I noticed there are two holes to choose from to locate the spring in the piece that makes up the spring tesion for this part of the derailleur. Again the two holes providing more or less spring tension. So again the same question, is there a benefit to having more or less spring tension here.
Not knowing my A$$ from my elbow I would guess I would want a high spring tension. Any one have an informed opinion?

But it is not supposed to spin when assembled. There is a tab on the jockey cage, just "below" the top jock wheel bolt that hits a tab on the body. I suppose it might spin if the bolt holding the jockey cage to the body was loosened. Re-reading your post indicates that might be the case.

That said, it feels like there is about a 2 to 4 pound resistance on my derailluer. A tight derailluer might have more "snap" when shifting, and less chance of chain slap on the chainstays, but a tight chain (too short by a link) would have the same effect, and let me tell you it makes a hell of a racket, and wears the cogs and chain fast. Expensive experence talkin' here.

Thanks, what I'm asking is when Re assembling. If you were to bolt it up as is it would be on the wrong side of that nub.
I E mailed Tim Laflin at Campy only. What you do is spin it past the nub and bolt it down. That provides the required tension.
