The first two years of the XS had sharp pointed pilot air screws which were very prone to breaking off in the orifice if they got tightened down too much. The last two years had blunt end needles with a pronounced step down, something that might be called a shoulder or ridge. I'm pretty sure the XJ screws were more like the later year XS screws.

I hope you didn't just file down a perfectly good screw! :-(
