Hi Warna, and sorry for the VERY long delay in welcoming you to our forum.
Sadly, there's not much traffic on here these days, and so I do not check for posts as often as I should....
The plug won't be black because of the heat grade of the plug. B6 or B7 are normal choices, but sooting can be caused by many things.
In my experience over the past 20 years, the most likely causes are the rubber sealing face of the enrichener plunger, but the worst cases have actually been caused by ignition problems.
The last two times I have had serious sooting problems have been caused by the coil breaking down (I replaced it with a Lucas from BL Mini) and failure of the condenser.
Hope that's some help in diagnosing your problems, and apologies again for the delay!
