Thanks, guys, these are excellent replies. I really appreciate the help. To answer a few questions you guys gave:

--Thanks for the correction on the "hydraulic" sprocket. Glad to understand it is spring loaded. See, I told you I would get stuff wrong.
--I have the cam holder, but what it the crank pin? I've never heard of that.
--We set it with the cam holder the first time, but did not do the revolutions before putting everything back together. That was our big waste of time. Now we have to go back and follow these instructions more carefully.
--Thanks, i'll check out the idler pulley more closely. These pictures came out WAY more orange than my car really looks. The sprockets are not really rusted at all although they look that way in these picts. In actuallity they are a dull yellow color with no rust.
--You're exactly right that my tensioner is too tight. We did the best we could figure out with the crappy chilton's and Haynes manuals, but I've now read the much better instructions on this forum and will follow your instructions.
--When I can finally get it running, I'll let you know if the belt ends running off center or not.

My friend (who is much more automotive-inclined than I am) is coming over tonight and we will work from all of your advice. Thanks very much.

If anyone has any additional advice, I will take all I can get.
