This is by far the most confused I've been when hunting a simple spark plug for a Craftsman 21" push mower with a Briggs engine.
The factory plug is a Champion RJ19HX, I currently have a Champion 5861 plug in it. I downloaded the user manual online and it claims a Champion RC12YC which has a much deeper reach.
E3 chat support said an E3.10 would be the direct replacement. Does this sound right?
