do you have a serial #, and what is it on for a mower??
I have a scag and it has rcj8y which is a champion. The parts men at napa tell me "the only thing you throw champions in is the garbage can".

good luck

as a side note, the champion plugs work good in my engine

just buy a champion Cj8 plug, it should work fine

I use nothing but champion cj8's myself. They work fine for me.

Champion# RN11YC4 or NGK# BP5ES Gap is .025
