Well that was a pain in the ass. Had to remove both the fixed cog and freewheel which was not fun as the fixed cog and lockring were put on with blue loctite. I've never messed with cone adjustment before, but it was tricky. I put some blue loctite on the cone lockrings so they don't come loose again - the wheel didn't wobble before recently and since just riding managed to loosen up the cones, I figured I wouldn't chance it.
Everything is back together now and she rides good. Hopefully the loctite will keep them from coming loose again.
