I'm having trouble sourcing spark plug washers. I've had the plug out so often that the old one is truly flattened and letting by. The only one I can find is an aero company at 39p each. Is this the only one available?Thanks for any help.George

We, why not just get a new plug? If the old one has been removed that many times, it must be nearing retirement age!

What can happen with an old plug that's been there a while is that you finally get round to checking it (say the evening before a run) and just the top half comes out.This can produce that sinking feeling.

Thanks guys. No, the plug is new. It's just that in fettling and re-fettling (ignition timing - twice, valves, compression testing etc) I noticed it was weeping an oil mist. Anyway, I followed the link from Baz and they have now arrived. I suspect that copper gives a better seal but I'm sure the steel ones will be fine.
