Since I was out in the Shed looking for something else, I checked, and my IF, 15-1 and two of my 15-30's operate by moving it UP to decrease stitch length and DOWN to increase stitch length. I have at least two more 15-30's but did not check them.
Now we need someone with a 15K30 to check and let us know if there machine does operate the other direction.
