I was wondering if there's anyone out there who has experience with a Glaskasten.  I can get mine to run great on blocks, but only for about 20 seconds when it runs low on steam and can't produce enough to keep a steady beat.  It's as if the exhaust is not creating enough draft to keep the fire going.  Running the blower will not create enough draft to keep the thing going.  It may be poor wick packing, but with the burner out of the engine, I get a very nice blue flame across all three wicks.

 

Also, it only runs on blocks, won't pull its own weight on a treadmill.

 

I've resealed the valve chests, and can't find any steam leaks.

 

So I guess the real queston is, are there any special tricks towards getting a Glaskasten to run?  I know about the fire brick trick, and thats next on the agenda, but I'm thinking that flame and wicks are not really the issue.

Scott, Mine had the same problem, I found that the smoke box was not sealed to the boiler. I stripped it down and added some fire proof gasket between the two. I think I may have some pictures if it would help?

I think the pictures show just what was wrong..
