Yashica GX film advance sprocket slipping

[lachlan]

Hey guys, I'm having a problem with a new black yashica gx from the bay that won't wind on film. Basically the film advance sprocket just slips, no matter the position of the film rewind button. The little hole in the plastic barrel lets me see that the inner shaft is spinning freely, the sprocket barrel just isn't locking to it...

Any tips of what might be wrong?

Could be the film rewind button hasn't reset itself.
If it were me I'd ask the Yashica Guy (look for his web site on your search engine).Nice chap.Very prompt replies.

Could it be that the "little hole in the plastic barrel" is where a set screw should be?
