Are you sure it's correct though, because if it was then it wouldn't be acting all weird. Have a look at the 4 "key" spokes around the valve hole, so on one side the one to the left of the hole, then next but one the other side, look at the hub where they are laced, then making a note of them, flip the wheel and look at their opposite spokes, now they're going left of valve hole and two holes to the right. You need to look at the hub where these 4 spokes go, they're kinda opposite holes but offset so they meet the rim in the right place, sounds like on one side you've gone one hole wrong, probably the second side you laced but that may depend on your lacing method. Check that on the second side the opposite spoke is slightly closer to its hole in the rim than the flip side. Does all that make any sense? I'm still half asleep.
