My nose tire was way out of balance as it came.  I was able to balance it by
jacking up the front of the plane and spinning up the tire with an air
powered die grinder.  I used one of those 1" drum sander attachments without
the sandpaper drum installed.  You can really get that tire spinning!  Then
using stick-on lead weights and trial and error, I was able to get it to run
smoothly.  I used double stick tape on the weights until they were where I
wanted them and then used the self adhesive tape on the weights.  So far the
weights seem to be staying put.

When I had shimmy I also had an out of balance front wheel. I removed it and
reinserted the axle in the bearings. I then bought two aluminum angle irons
about 3 feet long and set them up on my workbench, and levelled them in
every direction. I placed the wheel between the aluminum L's supported by
the axle and watched. The wheel turned. I got some aluminum weights from Big
"O" tires and applied them on the light side of the wheel, on the inner side
of the wheel. After installing about 3 weights I had a balanced wheel and
tire. 

The weights are held on by adhesive that is on the weights when I got them.
None have dropped off, due I suppose to the fact that they are held on by
centrificial force when the wheel is spinning.

This in addition to keeping the fork tight seems to have resulted in a very
much smoother front gear.

I suppose this is not as precise as spin balancing, but it worked for me.
