I understand it's common to use a domestic gas cooker spark generator as a fuel igniter. I went to the espares.co.uk website, & found loads. I then ordered the cheapest, figuring I would work out how to wire this up when I got it.
Having got it, it seems to need domestic AC mains to feed it. Not a good choice to put in a car. It hadn't occurred to me that it wouldn't need a low voltage DC source.
Can anybody recommend what to buy, please? Preferable a link to the espares website.
