Thanks for the generous offer, but it's not necessary. The problem's definitely in the lever. I'm think that I put one of the washers or cam-stop-thingies in backwards or in the wrong place. I'll tackle it tomorrow.

ETA:
In case I wasn't clear, my pair came set up for a high-normal FD. I took the left shifter off of the assembly housing to reverse the cam. After several failed attempts at getting the stack of washers and shaped bits and such back in the right order, I had the shifter moving in the right direction and turning on it's boss. It's acting like a friction lever with a loose D-ring, but the mounting bolt is fully tight. (Also, it seems to have no effect on lever tension, and just holds everything together. Another sign that I may have assembled it wrong.)
