Hi all, I was very recently given three pressure lamps by my sister in law. Two Tilleys and one Vapalux. What a revelation, I'm smitten. My wife just laughs at me, I don't care, I love tinkering with them to see if I can get them going again. I wonder if anyone can offer me advice though, any hints will be gratefully accepted. The first thing I did was to thoroughly flush all the tanks and re-fill with Premium paraffin. I've had no real trouble with the Vapalux, that's great. I've got the X246 Guardsman working with just replacing all seals, pump leather washer and Tilley mantle. I can't get the X246B to burn properly. I started by replacing all the seals, pump leather washer and vapouriser and cleaning the burner tubes. All spares were new, genuine Tilley. I hadn't a genuine mantle but had obtained some tie-on, after-market ones from a website for pressure lamp fettlers. I've followed the advice from Broadlander on You-tube (fantastic) with regard to starting etc. But as you can see by the photos it flames outside the mantle and has blackened the mantle. I've swapped the vapouriser for the original one but it still does the same thing. I've also swapped burner heads over. I'm waiting for some genuine Tilley mantles and will try again. I don't like asking for help, rather I like sorting it myself but I'm a bit stuck now. Any ideas? Thanks David.
