headset woe

I have a "cheap" titanium headset from ebay that I can't fit. It is either two tight or too loose, or at times, both (i.e. it binds and bars don't move freely left to right, but it is still not tight enough and steerer moves back and forwards when front brake is on)

It doesn't have a compression ring, and doesn't look like it is meant to, as the dust cover/bearing cap has a lip that inserts down the steerer tube inside the sealed bearing ring.

Ie it doesn't have the compression ring in the above photo.

It looks more like the Chris King below:

Hopefully eventually I will get this picture to work:

Help!
Anyone have any explanations

Bearings not coaxial?

Are you using a headset squishing tool?

Yes I used a headset squishing tool for the cups. What do you mean by questioning the coaxiality of my bearings...?

My guess for wiw is something in that stack of stuff is not co-axial. If the cups are good, then another option is that the crown race might not be seated correctly, but it is probably (maybe) a split one and doesn't need pushing down with a crown race pushing down tool. Or something.

cool. I will get the frame checked, it might need facing properly. The crown race is a split one and seems to be seated fine. Thanks v much for help and suggestions!

I find it weird that a supposedly premium chris king headset design has no compression ring, and tries to integrate it with the top cap.
