Small blades are tricky, but certainly not impossible.
Place a pointer near the crown of each wheel so you can see if there is any shifting of the apparent crown or excessive runout as you spin the wheel by hand (no blade installed).

If it appears the crown “moves around”, sanding the tire will let you restore the crown.

Also consider the possibility of failing bearings. Given you had tracking by hand then lost it when you applied power could indicate the wheel(s) shift a bit when under power, Simply trying to shift the wheels by hand at 9 & 3 o clock should let you know.

splintergroup, thanks for the suggestions. Sorry for the delay but sometimes life gets in the way.

I did not see any shifting or runout as you mentioned. As an added check I also looked at how centered the crown was on each wheel. Both seemed to be right in the center.

I checked for bearing wear as you suggested on both wheels at the 9 and 3 o’clock positions. And just to check myself I also checked at a few other locations as well. Of course I needed to put a blade on the wheels with a minimum amount of tension or the top wheel would rock due to the adjuster and tracking mechanism.

I’m contemplating sanding a flat spot on the tires as suggested by the manufacturer. Just thinking, not doing and open for any more suggestions.

Thanks.
