Stephen,
     Ah, the joys of tuning.  Some would say, hook it to an o-scope and be 
done with it, but personally I find it more fun (and much much much more 
educational) to tinker with everything.  Primary tap, spark gap (not too 
wide now), top load height, coupling (distance between primary and 
secondary), etc, all of these things will affect performance.  If you are 
not patient, and want it perfect, right now, you could plug it into java TC 
and get very close (it took me a while to figure out the program, there is a 
lot of stuff there), or get the proper tools (o-scope, signal generator, 
frequency counter?) to find the best spot first time.  Just remember, if you 
choose to tinker, changing one thing, will require a change in all the 
others even if it is small, but you will eventually stumble on an optimum 
value for all the components.  I hope this helps.
Scott Bogard.
