Hello and welcome JimO.
I had a few thoughts about this. Have you checked to see that your wheel is still level? I used to have a kick wheel but gave it up many years ago and switched to electric. If something was not level or became misaligned, it was difficult to center and keep the pots even. Have you moved the wheel recently or could the wheel shaft have somehow gotten bent? Maybe there is a screw or bolt that has gotten loose or worn out. If so, just the act of kicking the wheel could be enough to cause a little wobble to throw things off center.
I hope that your issues are just some easily fixed mechanical ones with the wheel and not complicated physical problems with your body.
Best of luck to you with this.
