When you say dialed down - you should hopefully see a relatively violet 
color to the flame, that is, relative to a baby blue rich flame.  Ideally, 
the flame should hiss a bit. Adjust the air up abit, the gas down. Try these 
adjustments after the burner has been on a few minutes.

Keep it moving. Back & forth & around.  It is possible to 'restore' the 
glass in a lean flame with lots of movement.

Well, for one you should build a primative hood up there.

Are they new & clean?

and the volume is ? i.e. smallest pipe diameter - particularly with regard 
to air.

Is it from a neon shop or distributor - then it's probably o.k.

Not really - it's a daunting subject - Just realize that a rich flame wants 
more  oxy, so it 'robs' it from the glass and thus reduces lead.

Okay, everyone you heard him. He's got the job.
