| alright guys, so i know there is already a spark plug thread floating around on here, but that dosent really relate to what i need.
SO, here we go i need to replace the spark plug in my push mower, the engine is a 6.5 horse, OHV briggs platinum. its about 5 years old, religiously maintained. (she is my baby) the stock spark plug is a champion RC12YX, and i cant find the damn thing anywhere. even on the champion website, i get "no results found". its like it dosent exist. ive read on various places that there isnt much differance between the YX and the RC12YC, which is a common, standard plug for almost ALL OHV engines. so i went and pulled the YX out of my push mower and the YC out of our Kohler V-twin, and waddya know, there almost identical. the only differance is that the center electrode is alot smaller on the YX. supposedly its like that to create a hotter, more prominate spark. i call snake oil. its also supposed to be "built" for a smaller, .20 gap, whereas the YC is "built" for a .30-.35 gap. really, the only differance is the center electrode. ive got a vid uploadin so i'll post that in here when its done. let me know what yalls think. would it be ok to use an RC12YC? | |

| As long as the heat range is the same, it won't hurt anything. I looked up the letter designations in the book. Y stands for standard projected core nose. C = copper plus design. X is for fine wire. | |

| The R is for resistance, if you ran a plug without the R on ur engine during a football match on tv, every neighbour came out and yelled at you, since they distorted the tv picture ![Very Happy](https://2img.net/i/fa/i/smiles/icon_biggrin.png) | |
