When I had the new diaphragm spring in the adjusting screw was able to touch the pushrod but after I had backed it out half a turn and locked it I then went to adjust the clutch cable but when I had the cable at 1/16" - 1/8" freeplay the clutch lever would barely move the diaphragm spring.
In order to get the diaphragm spring to move I had to tighten the clutch cable so there was no free play at all and even further which made pulling in the clutch cable extremely hard unless you were a gorilla.
When I put the old diaphragm spring back in the bike the adjustments were able to be made as specified in the service manual and everything worked flawlessly...
Do you think the new spring may have been more metal then spring as the thickness of it was the same as the original spring.
I was going to order an original Harley diaphragm spring and see if that works....but the old spring that is in the bike is an original HD spring.

Are you turning the screw in until it just touches the rod or until the rod pushes all the way pack to the umbrella against the tranny cover? When your cable is completely loose, pretty much disconnected, and you turn the screw all the way in (which means further turning will start actually disengaging the clutch), from there you should go half a turn out.

Are you checking the diaphragm spring tension? There are A,B,and C holes on the hub that set the tension (don't have the manual handy so forget what one to use when new) then you use a stait edge and feeler gauge to measure the spring deflection .010 from what I remember. If you are not doing this you will probably not be able to able to adjust the clutch.

Jokenroll,
I have the cable completely loose and I turn the adjusting screw until it seats on the pushrod and then I back it out half a turn and lock it. The adjuster plate is on the "B" position as that gives me almost flat ( no deflection). Then I adjust the cable to the free play as specified in the workshop manual .
Doing it this way with the new spring from JP cycles does not work but when I put back the original spring it works great so I can only assume there is something wrong with the spring..

I still didn't get it - what do you mean "seats on a pushrod"? The pushrod itself will have a back travel (while pressing back the umbrella and then the turning ramp subsequently), so you have to turn the screw until you take up all that travel. It is easy to check - if you turn the screw further than that, you should observe the diaphragm moving, i.e. the clutch starting to disengage.
In my case for instance, when the screw is in this position, even with the cable totally loose, I start feeling some resistance at the end of the lever travel.
If you absolutely sure you got out all the slack in the pushrod-umbrella-ramp combination, then yes, check your diaphragm adjustment - it might be to tight.
