Chris King no-threadset on carbon steerer, o-ring troubles

I'm having a bit of a battle with getting the top-cap over the steerer on a
bike I'm building.
This isn't my first King headset install, I've done maybe a half-dozen, plus
many other headset installs.

The darn o-ring is simply too tight. As in WAY too tight. I can get the
cap maybe 2-3mm down the steerer (put a nice bevel on it already), and
that's it, by hand.

I can't budge it with a rubber mallet. I can move it by using my crown race
setting tool, but it takes quite a tap to get it to move further down.
Given that, I suspect I won't be able to adjust the headset even if I can
get it snugged down, as there wouldn't be any play to even adjust?

Any ideas? I've tried greasing the o-ring and steerer, also silicone lube
on both. Same results with either, not going anywhere fast.

This headset was on the exact same frame fork model# awhile back, but I got
hit and it bent my headtube so I got a new fork to be safe on the rebuild.
I'm puzzled, any help would be greatly appreciated....

Thanks,
