Not sure if anyone else has tried this and it just dawned on me to give it a try:
I got it to run even more evenly by loosening the chain ring bolts to a little tighter than finger tight and rotated the crank to find the high/low spots then softly bumped the chain ring with a rubber mallet, then tightened the chain ring bolts. It helped. A few trial and errors and it's running pretty evenly.
