Sorted chaps Cheers. I pulled it apart again, worked the screw, so it would wind right in and whilst I was at it just popped the old hammer spring back in, it still looked good. Back over the chrono just over 6, adjusted till mid 11,s happy days. Oh apart from stripping one of the threads on the figure of 8 clamp grub screw holes
Just a little curious as to why previously my 400 liked a 160 fill, now prefers a 180, ideas ??

It could be many things from seals bedding in, to all the workings being lubricated.

What happens if you only fill it to 160?
