I downloaded them but see they are for gameport yokes. So now I have to
figure out the best way to clean and re-set my USB Yoke.

Yup, gameport.

I was just trying to diagnose if your problem was dirty pots or not.

Dirty pots will cause skips and jumps in movement. I wonder where you could
download a USB " joystick analyzer"... that's a map grid where you can
watch your control movements in real time to see if you have any dead spots
or spikes.
