Thank you very much strangeways!
I have been using that pinrepair link.  I printed the pinrepair guide, it has post it notes all over it, and is a bit dog-eared.   It has a good gottleib diagram of the vari-target.  I had a problem with one of mine.  I think I have fixed it.  Now have to wait till i put it all back together to find out.

cheers
