Champion J19LM or RJ19LM
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.
champion rj19lm or just a regular j19lm will work just fine in that engine.
I have used a Champion RJ19LM or J19LM, both work fine.
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.

The "R" just designates a resistor plug. You are fine with the J19LM.
The Champion spark plug rj19lmc should be able to replace j19lm. Many of Champions spark plugs are interchangeable with plugs with the same letter coding.
