The ratchet mechanism in the lever isn't engaging.
I had something similar happen to an SL35, which is cosmetically and functionally similar to the K1000, though (probably) mechanically not in various ways. Anyway I fixed it by removing the wind lever and other bits, then the top plate and applying some oil in 'likely' spots. The hardest part was reassembling but after several tries I got it right and the lever worked for a few more years.
