dial back timing light, what makes it tick...?

great! I knew of the venerable 555 but I never saw a micro or millisecond delay application. The spark event happens at the end of the pulse so I guess I would just have to extend the pulse or duty cycle of the trigger to get me a delayed event? Interesting.....further research....Ill take a look at my cheap HF dial back tach (or for that matter my dial back MSD box)...DUH! I had forgotton I even had that :p to see what it uses, probably a blob IC (masked to prevent pirating). we'll see as I dont really want to use that for this application.
