I've had the Petromax out, first time in ages. I'd not been using it as the pump was weak and in order to use the blowtorch lighter (the whole point of the Petromax design) you needed to pump like a lunatic. Well today my mind turned to it and almost immediately Google told me to massage the pump leather with grease, makes sense TBH.
Well it was like night and day, it still takes a bit of doing but it's quite achievable and you can watch the pressure build quickly. Oddly it wouldn't light off a lighter, it absolutely sucked the flame in but it wasn't catching, I just went straight to the blowtorch as it was to hand.
What a machine, just roars to life without any messing about with meths, doesn't fail to light leaving you with a too hot to handle but not hot enough to light lamp. Smells beautiful, gives out a fantastic warmth, enough light but pretty pathetic in modern terms.
I'm going on holiday again on Monday so I might take it with me.
Edit: tinnitus? What tinnitus, I've got my lamp lit, I can't hear shit.
