in order to clarify things, i attatched a picture of my engine.
the picture clearly shows the ignition module, the plug connection and the single magnet.
tested the battary today, even at 1A load, the voltage remains 5.2V

i dont think it really matters if the engine is a GT or a GT2, as lon as it work well and strong.
i only ask to have the rpm readings that i had before the ignition module was changed.
