Didn’t think this one would take much fettling. Replaced the filler cap seal, the burner seals and gave it a good clean out. Pumped up pressure and no leaks. 2 pint kerosene / paraffin stove. No model Number on stove Silent burner Made in GDR (German Democratic Republic) Steel feet made from split tube. Riser fixed with steel fuel pickup tube. Removable pot supports. Although the pot supports are removable the burner connection is a fibre washer (not lead) as found on the standard fixed leg #1 or #5. Note. The reserve cap is missing but would normally fit on the filler cap. The mounting screw thread in the cap is approx. ¼” / 6mm. When I sat the trivet on the pot supports it did not centre over the burner (really bad alignment). The burner was straight so wasn’t the problem. Placed a square against the legs and found the problem. Two of the feet were not soldered on square. Photo shows the worst of them. So won’t use the trivet. OK primed the stove and I had flame. It was rather yellow and didn’t improve. Replace the jet and it helped but still yellow. A closer inspection of the burner caps found a problem. The bottom edge the inner cap had a lip (can be seen in the photo of the caps above) that stopped the cap sitting flat. Remover the lip and the colour improved but still yellow. Now have blue flame.
