Here’s a Kolibri kerosene-burning stove I received from a seller in the stove’s native country of Hungary. Kolibri means “Hummingbird”. It’s an attractive little porcelainized stove with very 1950’s or early ’60’s styling.
Just click on any image for a larger picture.
Sadly, while I received two of the original inner caps, no outer cap came with the stove.
Here are some detail shots of the stoves workings.
The knob on the front controls the cleaning needle which acts to throttle the stove.
The stove was disassembled and cleaned.
Unthreaded and removed.
The unique shaped NRV (Non-Return Valve) from the bottom of the pump tube.
As the stove came without a complete set of silent caps, I made a pair of stainless steel outer silent caps to match the inners. The number and size of exit holes and the general shape and size of the outer caps I based on inspections of photos of complete stoves researched from the web.
The fabricated outer caps worked well. Strong full flame. Note in the photo below that I repaired the chipped porcelain around the pump tube mount with matching white epoxy paint, built up in layers and smooth and polished with ultra-fine abrasives and polish.
But, I also liked the performance of the stove with this 3D laser-printed BernieDawg prototype cap.
