Are you still using the fibers and steels that you got it with?
Double check your thicknesses, and fiber (7), and plate count (6) with the honda manual.
Also double check that actuator arm is letting the rod return as far as it can.
When you have the push rod pulled out and the cable disconnected you can lift that arm up and out and have a look at the rod pocket also while you are there.
I think you said it has the big thrust washer is behind the inner clutch hub, right? #19 on a parts diagram
Check those and let us know, I'm running out of ideas lol
