By the way - the tank I had in the backyard that was locked up
during winter - we are using it now. The central core expanded
into the cylinder around it that squeezed down on it - locking it tight.

Put it on the Barbecue and there be flames.
So in a 'pinch' one could pour a pan or water cooker over the knob
section to warm it up and get the gas available when freezing.

Butane gizmo. Got it at a yard sale. Not clear it ever worked.
Is full of Butane.
The orifice is two concentric brass parts screwed together
with a tiny metal disk in between. Disc is very thin and about .150
diameter. Has a TINY hole for the orifice.
50X microscope is the best I had handy. Can tell there maybe
was a hole..maybe...

How can I clean or ream such a tiny hole?
How did they manufacture it in the first place?

I'm guessing that the hole has to be very symmetrical
so the jet of gas goes down the center of the tube that mixes the air.

Not worth fixing, but could be a learning exercise.

Clean it with a ultrasonic machine. Try water, then 180 proof alcohol.
(Vodka works) Avoid sticking anything through itty bitty holes to
avoid making itty bitty burrs that can be a big problem. Your local
jewelry store can clean it.

Good call. Ultrasonic cleaner fixed it.
Plugged up again. Seems that the foam filter designed to keep
crap out of the orifice was depositing crap in the orifice.
Took that out and it's working.
Assume it will plug up from crap in the butane tank, but I'll
worry about that when it happens. For now, it works.
Thanks.
