Look closer. The inboard end of the shaft that carries the needle
fits into a tiny bore in the inboard end of the input shaft to keep
the magnet and drum concentric with one another. This close fit is
subject to dried-out lube or a bit of grit interfering with the needle
shaft's freedom and drives the needle up. Or it might be worn to the
point that it's chattering and adding friction, with the same result.

Thanks, Dan. If you read my other post to Cy, you'll know that since I
didn't find anything my limited talents could repair I'm choosing the
cheaper option of replacing it with a used unit rather than a rebuild.

Now if I could just get the rest of me repaired or rebuilt!
