My money is on the already mentioned slight bit of slack not been in both master and slave cylinder rods. Back to basics, don't overthink it. Check both rods rattle a little. My TR4 had this same issue it took me 2 years to figure it out.

If the pump is dry it may not pump, mine did not after last winter. I had to tip some petrol into it. Then it all worked fine.
