how to even deck in upper position

[allthumbs23]

I have a BX2230 and wonder if there is a way to get the mower deck to com up more evenly? As you can see in the pics one side bottoms out, but the other has a fair sized gap. I know how to lower the deck so there is a small gap at the upper stop, but I can't seem to get the other side to come up. Thanks for any help.

Check for bent linkage and may sure there are no rocks under the balancer bar.

I don't see either. My balancer bar is set even from side to side per tha manual.
