howdy all -- decided it was time to do a tune-up on my "new" 77 toyota -- when i look in my idiot manual, i see a description of something called a "spring damper" in the distributor, kind of like a second set of points, but without the points -- well mine is missing, seems to have been snapped off -- the screw and base of it are still there -- i set the new points, and its now running a lot better, but it bothers me that this spring thing is not there -- anyone know what it does? -- and anyone have a recommendation on a solid state ignition to replace these points?
