Any machine knitters willing to give a technical opinion? [View all]

I bought a mid-80's KH930 at an estate sale; I've been looking for a knitting machine because I'm primarily a sewist, and have become increasingly frustrated with the quality and availability of sweater knits. I don't knit at all (leftie in a family full of impatient hard-wired righties).

I've figured out most of the machine, I'm good mechanically, so have taken it apart and serviced it. I have a good grasp now of stockinette and the tuck stitch settings, so I know the machine is working well and the timing belt is functioning correctly, but my first attempt at jacquard (fair isle?) patterning looks... wrong.
