A12 distributor, vacuum advance question

Hey all,
I suspect the vacuum advance is playing up on the Datsun. How freely should it move? I'm thinking it shouldn't squeak?

Clean it up and add some lube?

most probably counter weights. take dissy out . disemble and lube counter weights and bushes whilst in there.

Meh dryballs.
[from memory the centre of the vac plate is a ball bearing Japanese hitatchi dissy type]

. Yep, the balls were very dry, and very hard to find when dropped! All back together and seems to be working.
