Well, I was having some odd burning symptoms so I thought it was my fuel pick up tube being clogged. Ran through the whole lamp, cleaned everything out and the lamp re-lit and ran about 30 minutes before going out. No fuel was coming out of the vaporizer so I decided to try to take it apart. Everything was stuck solid. Was eventually able to get the vaporizer out of the brass part that sits on it, but it took a lot of kroil and patience. The vaporizer is very swollen and sadly no longer usable. Is there a source for 169 vaporizers?
As a recent thread regarding 169 vapourisers said, Tilley are currently in the process of re-engineering their current 169 production. This is due to so many problems with the previous batches, wherever they were made (China?). NOS ones do appear on eBay, circa 30-35 quid posted uk.
