No problem, we are all here to gain experience and talk to each other. The magneto is the unit the flywheel magnets move quickly past, thus generating electricity in the magneto's coil. There are actually two coupled coils, one to generate a strong current at low voltage, and another, coupled coil to step that up to 10 to 20 thousand volts to make a spark. The diagram below shows a breaker-point magneto. Most modern ones use an electronic switch instead of a mechanical one, to achieve the same result. We need to think about what you may have done that stops your magneto from working. The first point is, how close to the flywheel did you put the exposed metal part of the magneto when you reinstalled it? It needs to be parallel to the surface of the flywheel, and about 0.012 inches away (the thickness of a visiting card). Second, did you earth the ground connection of the magneto (usually under one of its mounting screws)? Third, what did you do with the kill wire (not shown in the diagram, it is a wire from the bottom of the coil primary, just above the points - when that wire is grounded, it kills the ignition stone dead, which is how you switch off the engine when you need to stop it)? If you connected the kill wire to ground, that explains your problem.
