Here is a factory owners and parts manual for the Wico JEM. These made a brief appearance in some Wisconsin engines and Oliver tractors. Hopefully this will keep yours alive and well. They share many of the same parts as the model J4.
Beware of P/N X1413. Most black plastic cased devices found will be bad and cause a wimpy spark or no spark at all.The condenser for the more popular Wico Model C is a readily available replacement. The Wico C also uses the same points as the JEM and are still available.
