Briggs & Stratton Replacement Spark Plug 5095, RJ19LM, RCJ8

High-quality spark plug. After gapping it to the manufacturer's specifications, it was a perfect fit for my older Sears snowblower. The engine starts easily and runs smoothly. Highly recommended for its straightforward installation.

Briggs & Stratton 5095 Part no. 796112 Spark Plug. Since my father passed away a number of years ago, my mother being elderly at age 83, really can't mow the lawn herself. So either myself, or her grandsons take care of her lawn for her. She purchased a new lawnmower 2 springs ago, after the first season of use, it no longer started, so we had to take our mower over to her house to cut the lawn every week. My youngest son removed the old spark plug from the mower, he said he checked the calibration on the new spark plug, and said they usually preset them at factory now a days, so he didn't have to adjust the plug in any way. He then said he hand tightened the plug, lifted the handle of the mower, then removed the plug, making sure it had been seated well, and had gotten conditioned. He then fitted the plug snuggly back, being careful not to over tighten. Wouldn't have believed it, but he attempted to start the mower, first try it was running, a bit smokey at first, most likely from setting up for an entire year, as it soon cleared up. Everyone had thought it was a carburetor problem most likely, and instead it was from a bad plug. The earlier plug was a J-19 I believe. So far, were really pleased with this plug, even wrote the part number on phone, to insure trying this on our mower if it starts acting up. Costs less to replace a plug, than to pay to purchase a new mower. My review took longer than intended, but due to social distancing, as my mom is in here 80's.

I received a substitute plug, not the one pictured. it is not pre-gapped. I could have purchased 4 substitutes at the same price as this one. As I read reviews, this is not the first time to have that happen.
