I was told it is the balled up lead deposits in the spark plugs that
needs to be cleaned out while servicing them. This by a 50+ year A&P.

Perhaps I heard from a more contemporary source.

Dingleberry is a bit dated though, the new word is actually klingon.

Hince it is said that the simularity between StarTrek and a roll of toilet
tissue is that - both go around and around your Uranus looking for Klingons.

Don't know how that would relate to spark plugs.
