Why do used spark plugs have a weak spark?
Used spark plugs are hard to fire as the gaps are worn out, and insulation properties of the ceramic is compromised by solid combustion deposits and old fuel saturation. This robs available voltage at the spark plug gap, as it “leaks” through the low resistance carbon deposits to the ground, resulting in a weak spark.
