Hi Rich,
Is this an early clutch, all the ones I've seen are for the F1,
I would have thought that even if the springs were on the weak, while the engine was not running clutch operation would still work.
Dumb question coming......
You have the correct number of friction and plain plates. don't you?
I had a look in the Haynes, and the reassembly looks a lot more complicated on the earlier clutches
