Right I am banging my head against a brick wall
I am lucky if I can do 60mph
all plugs sooted up
I am getting no where
is there anyone in the Manchester area who could give me some help or a pillow for the wall
You've not actually answered anyone's questions?
Sooty plugs is normally caused by unburned fuel, so either too much fuel or not enough air.
How old is your air filter, and more importantly what brand did you last put in?
You say you're tuning the carbs, but what exactly are you doing?
Give us as much info as possible no matter how trivial, like have you had any recent work done on it, or changed anything?
