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.

What causes spark plugs to soot up on one side?
Soot buildup on one side of a spark plug typically indicates incomplete combustion, which can be caused by several factors, including an overly rich fuel mixture, improper air-fuel ratio, or oil leaking into the combustion chamber. Additionally, a malfunctioning fuel injector or a dirty air filter may contribute to uneven combustion, leading to soot accumulation on one side. Engine misfires or poor ignition timing can also exacerbate this issue. Regular maintenance and diagnostics can help identify and resolve the underlying causes.

Fouling spark plugs can happen when the tip temperature is insufficient to burn off carbon, fuel, oil or other deposits and causes spark to leach to metal shell...no spark across plug gap will cause a misfire.
