predator cylinder wall?

[predator]

if my plug is really black but not wet at all will the gas wash the oil of the cyinder wall and cause my motor to cease or blow? its black but i have not raced it yet i just took it up and down the road twice?

Your spark plug is black because the fuel is too rich

To answer your question, you'd have to be running extremely rich to wash down the cylinder walls. By the time you start washing down the cylinder walls, you're engine will hardly run.
