The magneto coil (high tension winding wrapped around low tension winding - all wound on a pole-piece ) go bad on these and short of winding a new coil the magneto is scrap. Do not despair because a 5ah gel-cell 12v battery and a "universal" ignition coil from NAPA will make sparks for hours of running per charge. MY ZZ came on an old US Army Signal Corps belt driven 110V alternator (Lol - "portable" if you got 8 guys and two pieces of pipe) so I just plugged a trickle charger into the 110 and I am good. PS - The flywheel nut on these units are left hand threads. PSS - I have the Repair Instructions for these and all factory bulletins. The cylinder head's spark plug hole has an "anti-fouler" built into it. It is a small chamber that isolates the spark plug from the combustion chamber and it is there in case the engine becomes worn and burns oil. One of the bulletins said to open the hole in the said ani-fouler up to 1/4" diameter.
the WWII drum corps could march to the beat of this little engine.
