- Burning with a butane torch – Some DIY repairers have also shared that it’s possible to burn off the excess carbon with a butane torch.

Plugs fouls out because the air/fuel mixture is too rich. Yes you can dry out a plug and re-use it but it may not perform as well as it should. Fouled plugs are black or wet, and don’t work properly because the carbon or liquid on them shorts the path and the spark no longer occurs across the air-gap, the purpose of a spark plug.
Why do spark plugs fire when the chamber is empty?
The spark plug firing while the chamber is empty simply has no effect, as if it never happened. Consider how much lighter, cheaper, and easier it is to do that rather than have a distributor rotor or electronic ignition like a car to make them fire only when needed.
