I suspect the slow speed governor needs a clean and oil. Can I get to the governor without removing the film counter unit and/or shutter speed selector? The governor is under there somewhere but the Canon service manual is not helpful. Removing the units looks tricky. I have the same problem with a Pellix and probably the same solution too.
