What happens when you mix alcohol with spark plugs?
Excessively lean mixtures may result in cold combustion from inadequate fuel. This can leave a wet, uncolored spark plug housing looking like a rich mixture, when the opposite is actually true. Slightly lean mixtures of alcohol fuels should leave no color from the fuels as well.
What does rapping the throttle on a spark plug do?
Repeatedly rapping the throttle is a tease to the carbon build-up on the spark plug porcelain. This spark plug is examined under a magnifying glass to inspect for porcelain, strap, and housing discolorations as tuning indicators.
What happens when you put gasoline in spark plug?
Gasoline mixtures up to a certain point on the lean side may increase engine operating temperature and show signs of heat on the plug. Without an adequate cooling system, a lean condition can cause overheating, pre-ignition, or even detonation, which could cause porcelain failure.
What should my spark plug look like after a run?
Engines that run hotter due to lower-octane gasoline may burn off more residuals in some cases, whereas more residuals may build-up from an engine using higher octane fuels. White porcelain showing no signs of carbon build-up, cracking, peppering, or oil deposits is considered an ideal spark plug after a run.

Where do you change the spark plugs in a car?

How are spark plugs used in port injection engines?
Port-injection engines inject fuel during the intake stroke, while direct-injection engines, gasoline or diesel, might wait until the compression stroke. Finally, heat is provided in one of two ways: one or two spark plugs for gasoline engines, or the heat of compression for diesel engines.
