What causes spark plugs to soot up?
Soot, or dry fouling of the plugs is a result of unburned fuel. The causes are (in order of likelihood) 1. Not enough air. 2. Weak Spark. Failed spark plug(s). 3. Too much petrol. 4. Ignition timing incorrect. The main thing to establish is the soot on all plugs or just one or a number. If all, then 1,2,3 & 4. If just one or two, or a bank if multi carbed, then focus on that bank.
