Brompton Freewheel Sticking

[Andy in Germany]

The freewheel on my 6-speed Brompton 'C' has gradually become sticky over the last few weeks. Is this a known issue, and is there any solution apart from replacement? It looks like a freehub system, but I'd like to know how to deal with it before I start taking things apart; do I need any special, Brompton/Sturmey Archer specific tools?

I had that happen on one (non-Brompton) bike when I overtightened the quick release.

The problem went away when I adjusted it properly.
