Why Carbon Deposits Build Up In Spark Plug? | Causes Of Carbon Fouled Spark Plug In Bike & Scooter

Carbon buildup on spark plug tips can make them ineffective over time. Once the spark plug of motorcycle (bike) & scooter (scooty) goes bad, there will be all sorts of engine misfires and poor performance.

Then, why do spark plugs get carbon buildup? The primary cause for black carbon buildup on spark plugs is the engine burning a rich air-fuel mixture. Another common reason is the spark plug is too cold and is operating at a lower temperature than required.

If the end of the spark plug is black, dry, and covered in soot – then the spark plug has carbon build-up. And this buildup is often dubbed as carbon fouling.

The carbon buildup on the spark plug will be dry and dusty with black in color. If you touch the buildup and wipe it on your fingers, you will feel it powdery.

The primary cause for black carbon buildup on spark plugs is the engine burning a rich air-fuel mixture.

A rich air-fuel mixture refers to high amounts of fuel than required for the amount of air present. When a rich air-fuel mixture enters the engine, the fuel will not burn completely. The excess fuel will either detonate after the combustion cycle or in the exhaust system.

This rich fuel mixture with incomplete burning leads to the buildup of carbon along the spark plug tip.

Carburetor tuning is vital for the engine to receive air-fuel mixture in the right proportions. If the tuning is off, the carburetor mixes the air and the fuel in the wrong amounts. Either it will be lean (too much air and too low fuel) or will be rich (too low air and too much fuel).

As for air filters, a clogged and blackened air filter is always a nuisance.

When the air filter is clogged, the first thing that happens is – that not enough air gets into the engine. The clogged filter is just not allowing sufficient air entry. As a result, the engine receives too less a quantity of air leading to a rich fuel mixture.

Dear MT sir
All information are provided from your side is awesome as always.
And, rest about a little suggestion about channel every video ending part with goodbye sounds little for me uncomfortable.
It maybe change with "see you all in next video with a new topic bye" that's it.
Although that's my Point Of View.
Rest of all yours
