I found myself in an auto parts store yesterday. Two people at the next counter (customer and shop person) couldn't decide whether points fired on open or close.
It's on open, of course.
The "old guy" part is that I was explaining how a battery/coil/points system actually worked, what a condenser was for, etc. - and afterwards realized that all the folks in the store had been born
after electronic ignition was standard equipment on, well
everything.
Maybe I'll go back and explain side valve engines or inlet over exhaust
