running too rich check the air filter could also be defective injectors
Catalytic converters clog due to the carbon that the car produces. Usually, when the carbon has built up inside the cat., black smoke will come out of the tailpipe when you rev the engine. In extreme cases, black soot is visible on the ground next to the vehicle's tailpipe. Crystal Woll
Running rich, depending on year of vehicle it's possibly a o2 sensor, fuel system problem, carb if so equipped. Time for you to do some diagnostics
You have worn valve seals and posibly bad valve guides.

To stop black soot from coming out of the tailpipe, first check and replace any clogged air filters, as restricted airflow can lead to incomplete combustion. Ensure that the fuel system is functioning properly, using high-quality fuel and considering a fuel system cleaner to remove deposits. Additionally, regular maintenance, including oil changes and spark plug replacements, can help improve engine efficiency and reduce soot production. If the issue persists, consult a mechanic to diagnose potential engine problems.
It usually means too much fuel or not enough spark.
Purchase Soy candles that burn smoke free.....Enjoy!! No soot!!
Black ash from a fire is commonly referred to as soot. It is a black powdery substance that is left behind after a material has been burnt. Soot can accumulate on surfaces and may cause respiratory issues if inhaled.
Yes, soot is a black carbonaceous substance produced during incomplete combustion of carbon-containing fuels. It consists mainly of amorphous carbon and is responsible for giving smoke its dark color.
Materials like rubber, plastic, and oil produce thick black smoke when burned due to the incomplete combustion of carbon-based compounds. The presence of soot and other particulates in the smoke can make it appear dark and dense.
Carbon-containing compounds, such as hydrocarbons or organic materials like paper, can produce a black flame when burned due to the incomplete combustion process generating soot particles that emit black smoke and flame.
You still have some soot on the very tip of your nose.
