Since I built my first internal combustion engine in 2012, I've been using automotive ignition points that originally were used on 1961 to 1972 Chrysler products. They were fabulous!! These points and the the same year of condenser worked with absolutely no modifications on the small i.c. engines I make. They worked so good that I modelled them in 3D cad, and just dropped them into an engine cad assembly whenever I needed them. And the best part was that the points and condenser together cost only $20 Canadian funds. Alas, this year they were declared "special order" parts.--I can still get them, but now they cost $40 per set---and that is too steep for my blood. I could bite the bullet and move up to electronic ignition with a Hall switch and magnet, but again, the cost ends up being prohibitive. I think I am now going to have to find a supplier of ignition points for a chainsaw or gas lawnmower ??? that will work on a 12 volt power supply, model them in 3D cad, and begin using them on anymore engines that I build. If anybody has a favorite set of inexpensive mechanical ignition points and condenser they would like to share with me, it would be greatly appreciated. It is not a problem to model them up in 3D and begin using them instead of my old Chrysler points.---Brian Rupnow
