Look what I found in the tank! About a teaspoon of mud and sand in an old X246 I've picked up on the bay of evil....
Not too bad. I have seen much worse come out of some lamps. Shows you though that it pays to clean a new find. ::Neil::
Bought also an used Optimus 930 which must have been fueled with the worst substance ever, looked like someone had dissolved an entire pump leather in there.
Two lamps I found completely clogged with green smelly slimy stuff. Had to use acetone to dissolve it. Finally I succeeded and the lamps are fine now.
