Carbon deposits on spark plugs are primarily caused by incomplete combustion of fuel within the engine. This can occur due to a rich fuel mixture, faulty fuel injectors, or issues with the ignition system, leading to unburned fuel and oil that accumulate on the plugs. Over time, these deposits can hinder spark plug performance, causing misfires and reduced engine efficiency. Regular maintenance and ensuring proper engine tuning can help minimize carbon buildup.

Why do Spark plugs burn out?
Spark plugs don't really burn out, they foul out. A spark plug is used to ignite the fuel/air mixture squirted into the cylinder by the fuel injector. The plug sends a spark and boom small explosion. However gasoline is not 100% clean, so it leaves carbon deposits on the plug. Over time these deposits foul the plug.
What is a fouled spark plug?
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. Wet-fouled spark plugs must be changed as they won't fire. Dry-fouled spark plugs can sometimes be successfully cleaned by bringing the engine up to the operating temp.

Spark Plug FoulingUsually there are two main causes of spark plug fouling:The engine is worn, and loose fitting parts allow engine lubricating oil to get into the combustion chambers [cylinders]. The oil then gets onto the spark plugs, and is "cooked" on.Another possibility is that the fuel mixture is way too "rich," causing incomplete combustion which deposits carbon and lacquer on the plug tip.
