What pulls the FD away from the FW...
Ok here is my problem:
New ACT clutch comptech fly, OE FD & TB and a new OE pilot in the fly all installed.
I developed a dragging clutch issue about a month later. The master and slave turned out to be part of the problem most likely caused by old clutch fluid contamination. I also relubed the fork as per hondas TSB using their super high temp urea grease. It worked great for about a week.
My question: (Aided by pic below)
When you depress the clutch, the fork(4) pulls back on the TB(3) that pushes on the PP fingers to release the pressure on the FD. The TB slides on a smooth collar(1) while the FD slides on the splines.
How exactly does the FD pull away from the FW? I

IMO that is correct.
In the service manual there is no specification for how much play there should be.
Could very well be the case.
In the service manual they state to put thin uniform coat of high temp urae grease on the clutch plate splines, slide it on the mainshaft and remove extra overflow grease.
Did you notice that being done on your install?
Clutch dumps and / or normal wear and tear may form ridges on the mainshaft and or clutch plate splines making it harder to move freely.

I do know the owner was in his 40's and considering the pre mature failure of the FD spring retainers I suspect many miss matched downshifts without matching rpm. This could possibly be the cause of ridges if there are any.
EDIT: I have almost 66K miles on it now.

The release bearing is installed behind the diaphram springs of the pressure plate. The fork pulls the bearing and the Pressure plate springs to release the clutch, not push.

My question is what happens to the FD when the pressure is releived?

When the pressure is relieved the disk should float.
It will be pushed away from the FW in much the same way a disk brake pad is pushed away from a rotor. If something prevents it from freely moving away from the FW and the two surfaces are still in contact then the FW can impart some amount of torque to the FD and result in a dragging clutch.

The other 10%... who knows
EDIT: In case anyone here wants to see. I posted some pics of the OE parts to solve an arguement between a bunch of tools

You should check to see that the pressure plate is fully seated to the flywheel. If not, you won't get full compression of the pressure plate springs - or nonuniform compression. The pressure plate friction surface doesn't move far, just enough to release clamp load on the disk. As someone said, similar to a brake pad. The pads don't actually move back more than a fraction of a mm in straight line conditions, but it's enough not to create significant drag.
Unfortunately when you went aftermarket, there's no guarantee the parts will work together.
