Has anyone ever built a scratch ingnition unit, or know how someone would go about doing it? I was going to build an ignition unit (if anyone knows how) for my 45 cc Homelite chainsaw engine. I know CH-ignitioins has ready built, and a kit that you can do it your-self, but the D.I.Y. kit is almost as much as the one that is already done. So, does anyone know how I would go about doing this, where I would get what I need, and what I would need?

Thanks for the help
