Black plugs means you're running very rich !
What have you done to the fuelling system ? Do you have an adjustable fule pressure reg turned up too much ? What other mods do you have ? What plugs are you using and what heat range ?

Cheers

You wouldn't happen to be the same shouty guy that came on here recently AND UPSET EVERYONE BY SHOUTING ALL THE TIME AND ASKING STUPID QUESTIONS IN CAPITAL LETTERS.

Sorry, just a thought... ;)

Certainly sounds like your overfueling, if you have any Haynes manual look at the front and it will give you a reason for all sorts of things happening to the plugs, same principle for every car.

What mods have you done??
