You could buy a Permatune.  They sell for around $50.  It is a clear
sparkplug that you install and make your adjustments until the color of the
flame is what the instructions indicate it should be.   When you are done
you put the real plug back in.  I haven't actually tried one, but will
probably buy one at some point.  Anybody out there have any experience with
these?
