After removing the spark plug & re-attaching the plug lead to the end of the plug..........Hold the plug by the insulated lead, or the insulated (white porcelain) part of the plug, & touch the threaded part, firmly, to the top of the engine, somewhere where you can see the central electrode, as this is where you need to see if there's a spark or not. Keep holding it, firmly pressed (to get a good ground) while someone turns on the ignition, & in neutral, with the clutch pulled in, presses the starter. If the spark is ok you'll see it jump across from the central electrode to the inside wall of the plug.
