No, the two DO NOT interchange.
The Zenoah uses a 3 magnet flywheel, the CY only 2
The dynamics of where and how magnets generate the current and trigger coils timing point differ between the designs.
:laugh: You can however use either COMPLETE flywheel / Coil set on either engine.
Tho mounting coil of either on the odd engine would take some fabrication.
