There is now a cross ref chart and the one you are seeking for ab RC12YC is an E3.20 .
Hope that helps.
p.s. Set the gap as per your operators manual for your mower.

My son and I have just upgraded from the conventional EKG plug in our competition Trials motorcycles, to the E3.38 plug. The bikes start easier and run smoother on the bottom end of the power range, which is exactly what we need for Trials competition. The E3 plug is even less expensive than the NGK!
Thanks E3!
