Reading Sparkplugs /6

[JJordan1173]

Hello All,

Anyone have a link to a good guide for reading sparkplugs on the internet? Pulled mine today. Guessing rich and oil fouled. Layed out in order left to right.
Thanks for all the help.

I'm a visual learner. This is one of the better videos on the subject from Steve Morris

The first thing to check is that the plugs are the correct heat range. If the engine is worn, try a hotter heat range, a lower number in NGKs. If it has 6s, go to 5s.

The first picture is too far away need to see the firing end of the spark plug.
Second picture still too far away but it looks like the spark plug on the left is fouled cause could be weak spark and or faulty ignition wire.
