Rebuild kits come with a light duty spring you can put in there, but usually if the piston and cylinder aren't gunked up gravity is enough to pull it down.

Generally a residue of smoke pellets can build up in the cylinder from being overpacked at some point in the past. If you pull it apart and clean that out then it should all move pretty freely.
