I know there are lots of pre 1982 Briggs & Stratton lawn mowers out there that have conventional ignition points and condensor setup, and all they might need is a simple fix to the ignition, because there is no spark. Take a look at this video from "DavidsFarm" as I thought he did a pretty good job of explaining all this. I especially like the part where the camera chases down the flywheel as Dave puts it on the ground (edge up)and it starts to roll down the driveway! If you like it let us know on the mailing list and I will put up some others by Dave! The guy really knows those small engine repairs, plus amazingly a whole lot more!.
