Hi all, Looking to tease the brains trust with this one, I'm at a loss. I'll do my best to give as much info but keep it brief too. I've got a nice 236, has had a fair bit of use but was pretty mint and came up nicely with a full deconstruction and clean. I initially rebuilt the generator on it, cleaned and removed old packing then wound the spring with bronze wool, this was no good the lamp burned erratically and lean, almost completely blocking one air tube cleaned it up, but I wouldn't settle for this. I then replaced the gen with a reproduction one that had no packing and a much larger spring, this ran like garbage with big flares and spluttering. At this point I double checked the fuel air uptake assembly in the fount, which I had cleaned, though it was sparkly clean to begin with. I enlarged the spring a little bit to ensure the needle was lifting as it should, all seems fine. I took the original spring from the gen, along with new cardboard packing and bronze wool wound around the top section of the spring and coupled that with the new repro gen tube, jet and needle. This has got the lantern running ok, mantle is burning clean and bright, however there is still an intolerable flicker much like a candle with a draft. There is also still a bit of a gurgling sucking sound which is periodic. I just don't know where to go from here and haven't come across a 236 before so don't know what I should be expecting, but I'm certain it should run better than this! Any advice would be greatly appreciated!
Using a bulbous mantle such as the Petromax or Anchor type of 500 cp., mantle rather than the Coleman 500 cp., mantle may help, as a more bulbous mantle should form closer to the vapouriser / generator and therefor keep it hotter.
