a 5/8 socket
I found lots of replacements for the Champion rc12yc but none for the yx. Are they the same spark plug? Why wouldn't anyone carry a spark plug for a lawn mower that's two years old?
Should be 5/8
try spraying some wd-40 where it screws in and let it sit for a day. then see if it will come out
A good lawn mower spark plug will have just a small amount of brown deposit. In addition, the gap will be very close.
On the bottom of the mower, it takes 3/8" socket driver (no socket) to remove it
Would you use lawn mower plugs in your car?? NO!!!!
