Re: Testing testing testing
In my experience, when it comes to lawn mower ignition, a couple of things are more likely to quit before a quality spark plug. The first is generic corrosion of the wiring caused by dis-similar metals exposed to moisture. The second is work-hardening of the copper wiring in the coil(s), leading to breakage. The third is timing issues caused by hitting a large object with the blade, bringing everything but the flywheel to a sudden halt. Momentum keeps the flywheel moving, which bends or breaks the key that keeps the crank & flywheel positioned properly with respect to each other. The forth is the magnet(s) in the flywheel becoming dislodged by the same sudden stoppage (rare, becoming more common, see below). Lastly, the magnets can actually lose their magnetism over time (I saw it only once before the rise in Chinese motors, now I see it a couple times per year).
