Gleaned a few months ago as a wreck (all the upper part of the carburation is missing, and the preheating cup too) After a bath and cleaning : Yesterday I received the missing parts from Fogas.se, first run : "Hello Houston, there is a problem" !!! A nasty hallo around the mantle, then a huge carbon deposit !!! After investigation, it turns out that the 200/250 CP jets supplied are calibrated at 250 CP. Not compatible with a 200/1200 CP Optimus burner. With the right jet and needle, everything is back to normal !! A new rescue achieved.....
