It seems likely that you need the Ignition Update kit.

Alternative, with no guarantee, is to replace the stator with a known good 'original type' stator. If you are lucky, that might solve the problem. But, the original stators are known to fail over time, so the replacement 'old style' stator may or may not last very long.

It is also possible that the old CDI is failing, either by itself, or in conjunction with the old stator.

The best bet is to install the Update Kit.

Where is it possible to find this ignition update kit ?

I would do the "ignition coil tests", I believe it will also test the ignition wires to verify those parts are good.
Having 2 working cylinders you should be able to compare voltages from the CDI to the coil.

My bad for skipping over these basic checks and jumping to the Ignition Upgrade Kit
