If you damaged a Champion RJ19HX spark plug, then you can indeed replace and substitute that with a Champion RJ19LM spark plug due to the similarity in their sizes.
Rj19lm
yes
Throw any RJ2YXLE away that you come across and install a RJ19LM. Problem solved. I work for a company that sells briggs products and we have replaced, literally, hundreds of these this season. It's a horrible design. There are a few other plugs that will work as well, ( RJ19HX for example ) are more money, but you can rely on a good old RJ19LM to get the job done. Hope this helps.
Yes. Or a 5861 which is the plug number to replace RJ19LM, J19LM, RJ17LM, J17LM, RJ19LMC, RJ2YLE, 799876, or RJ2YXLE, SOURCE- I work at Pepboys and it says directly on the package.
yes
The J19LM and QJ19LM are Champion brand spark plugs used for garden machinery. The difference between them is their resistors, the J19LM use a regular resistor while the QJ19LM uses a CDI resistor.
