So the coiled piece had just broke free from the solder and you resoldered it and it works fine ?

Bob, It works fine but is clearly not going to be as accurate as it once was.
The earlier repair also did not likely leave it as accurate as it once was.
I recall Mirko saying that the fact that it is there is more important than that it works and that many of them do not work anymore.
 
I was fortunate the passage from the body to the coil did not plug itself with solder.

.
Tonight I repaired and tested the burner.
 
With solder, a torch, and some flux, I fixed about 10 leaks on the soldered seams of the burner.
It isn't pretty but looks better than it did and no longer leaks!

Hmmmm..... that doesn't seem hot enough. Is the wick just in the verticle tube ?

The wick goes to the bottom of the tank.
When it is hotter more alcohol vaporizes.
There is very little alcohol in the tank and the small warm up wicks may need replacing.
I had to tilt it to get some alcohol to the wicks.
When I steam test it I will find out if the combination of more alcohol and confinement of the firebox will let it get warmer and burn nicely. Will update as I test it hopefully tomorrow.

There may still be an issue with the amount of flame and I will not know until I give it an in service test.
 
I have not used this burner design before so I am still learning and I agree that it needs more flame to be effective.

I think we exagerate the need of pressure gauges for these toys as they have functioning safety valves. But I admit I follow mine on the engines that have them ________________________________________

Those of us with the slightest sense of engineering in our heads, do like to monitor these nice little engines.
In addition, to any collector, if it came with a gauge, it must have that gauge.
