I went to ACE and showed the clerk the plug I have (696073) the clerk then handed me a 5092 Champion part# 496018S made specifically for Briggs & Stratton. It says on the package that it fits all B&S OHV engines and it replaces a RC14YC....so I guess RC14YC is the cross reference answer that you are looking for? The new plug package stated: For models 120699, 121600, 122600...It's not real clear and I'm not exactly sure what it means for the models? Before trying this plug, I wanted to do a little research and make sure this is the correct plug, but I didn't find a whole lot of info on a conversion for this plug, except for the info on the new plug package. I haven't tried the plug yet, but it should be an exact replacement and work fine....I hope so, I'm in the middle of a pressure washing job and need to get this done. I'm too lazy to look right now, but I guess the next thing I will look at is what model do I have...engine model I guess they mean? I looked on my B&S 8.75 engine and didn't find a model # like the ones above. I also looked around on the net for a while for a plug for the engine I have and didn't find that either...so I give up looking and feel pretty good with this new plug. It cant hurt because my pressure washer won't start, even after 15 pulls. I hope this info helps you find what you need.
what is the champion cross reference for a briggs and stratton spark plug 691043
Champion RJ19LM
Rc12yc
Rc12yc
It is a platinum version of the Champion CJ8.
RC12YC in Champion
Champion RC14YC NGK: BCPR5ES
Champion RJ19LM
It crosses to a champion RJ19LM
Champion rj19lm
There is no Champion spark plug with the part number 696798. There is a Briggs and Stratton part number 696798 that does cross reference with a Champion RJ 19LM.
I'm thinking p/n# 5861 by champion.
