To troubleshoot a hard-starting KYMCO Scooter, begin by removing the spark plug and installing it into the spark plug cap. Then, test for a spark by connecting it to the engine ground. This helps identify issues like a faulty, fouled CDI unit, or a weak spark related to a faulty A.C. generator, broken ignition coil, or shorted exciter coil.
