The Park Tool website has lots of good info for those who are not experienced with bike mechanics.
A threadless headset is simple to adjust. Tighten the top cap bolt sufficiently to elimintate ALL play, then tighten the stem to retain the adjustment. It would be better to have a small amount of binding than any amount of play which will beat up the bearings quickly.
There are a couple or common reasons that yoy may not be able to remove all of the play. If you did not cut the steering tube (or install the proper amount of spacers under the stem) to leave a 2-3mm gap between the top of the stem and the steerer, the top cap may be in contact with the steering tube instead of the top of the stem, so there is no more adjustment available.
Another posibility is that the expanding plug that the top cap screws into is slipping. The LOOK expanding plug that I'm familiar with was prone to this problem. The top cap bolt serves a dual purpose to expand the plug and tighten the top cap. Other designs like Colnago's are superior. The plug is first expanded by tightening an internal hex and then the top cap bolt is installed to adjust the top cap tension.

|Is there a good site for campy questions?|

|Rarely does the Campy website fail to have the answers, either in the FAQ section or in the tech section. The tech section includes installation and maintenance instructions in PDF fomat.
www.branfordbike.com also has a lot of good info.
I haven't visited www.campyonly.com for awhile, but there is a fair amount of info on the site.

|You have to have some clearance between the bottom of the top cap and the top of the steerer tube. My guess is a 5mm stack washer either above or below your stem will solve your problem. If you like the height of your handlebars now, there is a school of thought that you are better off with one stack washer above your stem so that the stem clamp can't squish the top of the steerer tube.|

|the spacer on top will allow everything to be pulled tighter along that plane. Most manufacturers are recommending, NOW, that you put a spacer on top so the top cap isn't in contact with the carbon steerer anyway! Mine is set up the exact same way on my HSC3 and it hasn't moved!|
|A Big Thanks!!! It worked!!! Can't wait to ride :-)||rwebb|
