I’d be grateful for your help with a Tilley X246B Mk I, which I have been trying to service/renovate. It appeared in quite clean condition when I got it, but I suspected the vaporiser was not working as it should as the stopcock was very tight when turning off and the wire seeming a bit buckled. After cleaning everything I could, replacing all the washers etc and adding a Tilley 146X mantle, it worked after a fashion, without visible leaks. The problems were that the light was yellow and not as bright as I recall this type of lamp should be (it was not as bright a a correctly functioning Aladdin, and I recall the Tilley should be brighter than that). More of a problem was the light pulsed. Not so you would notice it when looking at the light directly, but very visible from the light on the walls. Sometimes this is even audible with a shoosh-shoosh sound about twice a second. After reading around here and confirming the vaporiser might be at fault, I got a new (old stock) 606 vaporiser and tried that. Initially, I was encouraged to find the stopcock now felt much better and the light was whiter, indeed more blue to the top of the mantle, but it still pulses — even after 70-80 pumps, which I understand should be sufficient. I assume now, having replaced the vaporiser, that only leaves a problem with the burner head? I wonder if you have any thoughts that might help please? This is my first post to this forum and so I thought it might be good to tell you something about myself, and my interest in this area, by way of an introduction. When I was a child in the 1960s, we lived in a place with no electricity and paraffin lamps and stoves were all we had. While I was too young at the time to be involved, they held a fascination for me. Later, we moved on and I never had much contact with anything like that again. Now, retired and in later life, I thought it would be fun to re-explore these fine things again. To begin with I bought a new Dietz hurricane lamp (a disappointment, it seemed much more tinny construction than my memories suggested) but works okay. I then started to look at Aladdin lamps — these were always my favourite, with their slender elegant designs. After buying a couple and some parts they are now working beautifully. An interesting observation: my wife had never seen a paraffin mantle lamp before and was amazed how it could put out so much light! After that, I bought a Primus No 5 stove, which with a service kit now works well. The only thing that does not seem right is that it seems too quiet! I think the stoves I remember must have had the “roarer burners” rather than the “silent burner” on the No 5. Last, I bought the Tilley lamp. I opted for the X246B as I guessed that it might be the least challenging for me to get started with; however, I have subsequently read that it’s not thought of as one of the better Tilleys. None the less, I think it is capable of working a little better than it currently is. If anyone could give me any hints that might get rid of the pulsing, I’d be most grateful. Many thanks to the moderators and to all who post to this forum, it’s really a mine of fascinating and entertaining information.
