∙ 11y agoThe 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.
The RJ19LM has an added resistor to reduce radio interference. You can use either model for your application as they are interchangeable.

Difference between paging and what?
There is no difference between them!

nothing, the difference between this plug and a rj19lm is minimal, but it has an extended electrode and a wide gap .040 instead of .030. You could theoretically use a 19lm with little issue but I wouldn't recommend it.
The "R" just designates a resistor plug. You are fine with the J19LM.
Rj19lm
Champion spark plug RJ19LM is for lawn mowers or similar equipment. The standard gap is .030 inches or 0.76mm.

yes
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.
yes
Champion RJ19LM will work.
