Ya there is something wrong with that Your current should stay about the same all way across the board. I usually run:

12 v 2800 rpms about 1.2 amp
24 v 5200 rpms 1.3 amp

You may want to check for short to the stator, or you may need to adjust the back plate beyond where the magnets stop the bolts. So you have to use clamps for temporary.
Last check to make sure the commutator sections are not narrower than the brush's. If thats the case you'll have top use 2 for off period.
Dip you bearings in light weight oil, sometimes factory ones are sticky.

I am leaning towards the short because of the current behavior.

Keep me posted.

If you have blocked him already add this to your signature and encourage others to block him as well. His onslaught of rambling in large text and his constant attempts to misinform at the excuse of being stupid should no longer be tolerated.
