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.
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.

Yes, the NGK BKR5EGP can be used as a replacement for the Champion RJ19LM spark plug. Both plugs have similar heat ranges and dimensions, making them compatible for many applications. However, it's always best to check the specific requirements of your engine to ensure optimal performance.
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.
The Briggs & Stratton spark plug part number 5066 cross-references to several other spark plugs, including the Champion J19LM and the NGK BPR6ES. These alternatives can typically be used interchangeably in applications where the 5066 is specified. Always ensure to check the specifications and compatibility for your specific engine model before replacing spark plugs.
The right spark plug for a 3.5hp Tecumseh engine is typically a Champion J19LM or an equivalent plug. However, it's essential to verify the specific model of your engine, as some variations may require different plugs. Always consult the engine's manual or manufacturer specifications to ensure compatibility.

The Briggs & Stratton spark plug model 798615 can be cross-referenced with several other spark plugs, including the Champion RJ19LM and the NGK BPR4ES. When replacing spark plugs, it's essential to ensure that the specifications such as heat range and electrode configuration match your engine's requirements. Always consult your engine's manual or a trusted source for compatibility before making a replacement.
Spark plugs come in three sizes: 5/8, 3/4, and 13/16. I think the RJ19LM takes a 13/16 socket. However, it would be wise to have all three sizes of sockets in your tool box - you never know when you will need one or the other.
