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?
If the jet is not clogged (happens often the first times after a full fettle) And there is no leaks on/from the filler cap? - I would check on the wick again and also change the top plate with an original - just to make sure the thick brass burner bell gets enough Thermal feedback from that new plate.
I had pretty much given it up as a bad job but I just couldn't. I fixed the SRV which was seized by putting it in my ultrasonic cleaner for half an hour to free the threads as it wouldn't budge. The cork pip was perished and has to be carefully picked out. Having replaced it with a new viton rubber pip I took the control valve out, removed the wick and dunked all the bits in the ultrasonic cleaner and made sure there was nothing blocking the fuel path. Once the wick was in, i assembled everything, filled it with fuel and primed with meths... look at her go! OK, the flame might be wonky and has yellow tips but this old girl is nearly 100 years old! She's 28 years older than me and i was born in 1958! There's a tiny, intermittent leak of fuel getting past the jet threads which robs the main flames of oxygen but I gotta say, I'm pumped! Id given her up as dead and now she lives again. Bot am I happy, I hate giving up on things.
And that's the point! One should not give up.Congratulations on your persistence. By the way. Does anyone know effective methods to seal the nozzle threads?
Hi @Knee To help seal the jet in its threaded hole it is worth trying a coating of copper grease on the threads before carefully assembly. This “fix” is not harmful (as long as you do not over-tighten and remember you are working with small threaded components made from soft brass) Best Regards, Kerophile.
@kerophile . Thank you very much for your reply. I will definitely try out the methods with copper grease. Greetings
