How do I do that?  Touch the sparkplug to the engine block while the engine is idling?

If you have a test light you can pierce the spark plug hood with the pointed end of the test light while the motor is running.  That will kill that plug.  If that plug that you pierce make no difference in the way you motor is running you will know that plug is not doing it’s job.

hope this helps.

Just curious Dale, what does that operation do to the test light bulb?
Don’t think I’ll try it on my new light.

Prepare to be boarded!
