I’m sorry for my ignorance on the following. My only excuse is that I’m generally more of stove guy. That said since finding a 1950s Petromax 350cp at a local carboot a few weeks ago I’ve caught the pressure lamp bug recently! Other than the petromax I’ve been getting a few lamps going that have hung around in my father’s shed for several decades. These have mostly been Tilleys which I’m happy to say are now shining again. The last of the shed lamps is a Bialaddin 310. Having replaced all the seals and pump leather it lights but sadly leaks fuel. I initially thought it was the seal where the fount meets the vaporiser however I’ve now realised it’s the nut where the control column attaches to the vaporiser (By this I don’t mean the knurled sleeve which holds a viton seal but the part which this screws onto). It appears to have originally been soldered in place but it appears to have been unscrewed at some point thus breaking the solder seal. My question is: is the control cock/ vaporiser on the 310 the same as other bialaddin models? The 315 looks quite similar? The assembly is fairly beaten up so I’m considering replacing it and keeping the original to repair at a later date.
