I bought this from the internet because it was so cheap. The main stem was bent, it was missing the flame spreader and it's missing the control key. I found a modern flame spreader and gave it a go but it barely worked at all. It looked very much like it was blocked due to being run on unleaded fuel. So today I stripped it down and replaced the wick before deciding to check the fuel path first. Surprisingly, with the valve open and the jet removed there seems to be no blockage at all so I reassembled it and hoped it would work but this is all I'm getting... Pre-heating with meths. Full on! Any suggestions?
