Maybe, there it's only one cylinder running. When the engine in running, unplug one sparkplug. When the engine dies, this cylinder runs. If the engine keeps running, this cylinder is not running.
In this case change the spark plug from left to right and repeat the procedure. When the mistake goes to the other side, the spark plug is broken.
Thanks Mattis,
I tried.

If I unplug the right spark plug the engine stop immediately.
If I unplug the left spark plug the engine continue running (even if it seems to feel a bit the difference).

I replaced both spark plugs with some old ones I had available but everything remain the same.

What can be the issue?

Thanks!

Luigi
