Spark plug inspection

~1min read
Caution
  • Do not inspect, adjust, or clean the plug gap with a wire brush. Doing so can damage the platinum tip.
  • When cleaning a spark plug with a plug clear, clean the plug quickly for less than 20 seconds with air pressure below 58.8 kpa {6.0 kgf/cm, 8.5 psi}. Verify that there is no carbon, sand, etc. in the spark plug after cleaning.
