On most lawn mowers there is no timing - they have the flywheel set, as long as the shear pin is in place, it will put the magnet by the coil at the proper time to fire. The points are run by the gap (you set the gap on the points) and the pin pushes the points open at the proper to fire. The only setting you have to do is the gap on the flywheel to the coil and the gap on the points.
