I re-adjusted the chain this morning and will run it. This is driving me nuts though. I gotta find out why it's doing this. Crank seems ok, sprocket ok, chainring ok, chain ok. The only component I haven't check is the crank spindle. If it was bent though, I would think that the crank itself would wobble. I'm also going to string-check my frame to see if it's out of alignment. I'm going to keep digging. Thank you for all your help though!
