Diagnosing a wheel problem?

So here it is:
*
The wheel on a new unicycle sits far too close to one side*, about 3/4"
space between the frame on the Left side and less than 3/8" on the
Right side.

*When the wheel is flipped the gaps also switch, keeping those same
dimensions, but on the different sides*, now 3/4" on the Right 3/8" on
the Left.

*This would indicate a problem with wheel and not the frame*...

*What should I be checking, adjusting, etc.?* What are the obvious
solutions--- it's a Qu-ax 20" Trials with the yellow hub --- if anyone
else has run into this problem or could share their
knowledge/experience, it would be great to read it.

It's dished incorrectly. Tighten up all the spokes on the side that has
the bigger gap by about 1/2 turn each, then check again.

Good point but don't just tighten the ones on the too big gap side to
fix it. First, tighten those as mentioned. On the next iteration,
loosen all the spokes on the too small side. Then tighten the too big
gap side again. Then loosen, and so on.

Thanks. Seems to be it.

So..................

The LBS couldn't fix it cheaply: With a new wheel, if the cost of
fixing it is less than the hassle of returning it I'd consider the
option-- it wasn't. I returned it. Just over two weeks later, it came
back. Whatever UDC did to fix it, the wheel is still offset on the
frame with a 2.5:1 gap ratio favoring the left.

I don't know what UDC did; I'm thinking it needs to be rebuilt, but I'd
rather defer to the forum for a an informed opinion.

Ideas?

Pictures please? Honestly, I don't see what's so weird about it. It's
just improperly dished. Just get out your spoke wrench, and you can fix
it in like 15 mins. Machine built wheels can't be expected to be
perfect all the time.

The frame isn't the same lengths on the bearing brackets, you need a
small (1mm thick) shim to put in the bearing holder.

That's unlikely where the gap changes side when the wheel is flipped.
The original assessment about dishing the wheel should fix the problem.

But the problem is the same on the other side if he flips the wheel.

I think it's still a problem w/ the spokes.

I had this same problem on my b*ke. The rim was rubbing the brake pad,
but on only one side. So I did as Harper said, but only going in 1/4
turn incriments, making sure the spokes retained the same overal
tightness. But now it was rubbing on the other side only. 45 minutes
after starting it was near perfect w/ a +/- 1/16" wobble, only
noticable as a slight pulsing when I apply the brakes.

Just add a shim anyways.
