Lever Shock Rejuvenation

Hi List,

Newbie here with a MarkII Sprite I just pulled out of storage after 13 years.
The front shocks were replaced shortly before it went into storage, but now
have no damping left.  I assume they have little or no internal wear, and was
hoping a seal had just dried up and some oil was lost.  Tried topping one up,
but didn't seem to help.  Any suggestions?

Sorry if I am coverring old territory.  I can't seem to find archives for this
list.
