1. Check that take up spool has axial play (i.e. up and down) mine has about 1/16". If it is tight axially that may be the problem, and you may need to file, ... after removal as below. Try to keep spool aligned with film rails if this is case.
It might be too slack, or tight.
2. Remove three screws underneath plate securing the bottom of take up spool. Hold spool in place in case it is spring loaded, this should be clear as the screws are slackened.
After the plate is removed the spool should drop from the drive and you may find that you have the normal Kiev drive fork mechanism and clutch to strip, and rebuild, which is possible with care without removing the top plate.
The clutch noes not need to be too tight, mine is really slack.
If you have a length of film you can try the first friction setting marking the performance with a pencil on the face of the film through the shutter opening on 'B', removing the film and measuring the spacing, the setting needs to work at the start and at the end of the film.
Good luck, I cannot strip my camera as it is under 2nd hand sale warranty.
For the last 13 months I've only used a Kiev (or Contax), apart from folders, Fed's, Zorki's, M2, etc.,... and a digital to record dismantle sequences...
