Are you sure the problem is not:
The kill button
The spark plug cap
The spark plug wire
The wiring between the mag and cdi
The mag
The cdi

So you changed out the spark plug and it runs again?
If so, it's not the first time a brand new spark plug has failed. Nothing is perfect in this world, even one of the most reliable brands of spark plug made are not immune.

Sounds like the plug is fouling. Try a heat range hotter plug. Try a B6HS or B5HS.
What does the plug look like? Picture?
What oil and ratio are you running?

Follow Pablo's lead. The oil ratio you are running is fine if that it what your particular oil of choice recommends. The jetting of the carburetor has a profound effect on proper combustion and spark plug fouling. The heat range of the spark plug is important too.
If it is too cold it cannot keep itself clean, if it is too hot it can do damage.
I too ask, can you share a photo of your spark plug, the sparking end of it?
It may be too cold or your carburetor is tuned too rich. The color of the combustion residue left on the spark plug will help determine the next course of action.
