Review: My mower suffered from weak / no spark, so I purchased this replacement. I used this part in my Sears-Craftsman 6.5 HP / 21" mower, model #944.362400. I think that this mower has the Briggs and Stratton "Quantum" engine. The "590454 Magneto Armature Coil" replaces original part# 802574 on this mower. Note that it looks different from the original part on the mower. A youtube video recommended setting the gap between this part and the flywheel to .012 inches. Others stated that the Briggs and Stratton manual calls for a .010 inch gap. I gapped it to .012 inches and it worked immediately. The part came with a note stating, "Air Vane Replacement. If replacing the armature on an engine built before date code 101230xx, the original air vane must also be replaced. Order and install 790848 Air Vane (sold separately)." I believe that my engine was built before that date, but it has no air vane at all. So, check before you purchase an air vane. You can find out about how to read date codes on the Briggs and Stratton web site.
Review: Dropped right into place on my Briggs and Stratton powered Craftsman mower (about 10 years old). Took about 1.5 hours to install. This includes removing the cover, fuel tank, oil fill, etc. Removing the old coil and installing the new coli and putting all of the parts back on. I used a business card to space/shim it away from the flywheel. It started on the first pull and ran better than it had for a long while. It comes with a spark plug socket and boot on it, which was perfect for my machine. It comes with an alternate clip. It is packaged in a thin cardboard box and is wrapped in a plastic bag. There is no instruction sheet with the product. You will need a maintenance / repair manual to point you in the right direction if you are not used to pulling apart your mower. Or you can find instructional videos on YouTube. At first I thought it was a fuel problem. It would start on the first, second or third pull. If I shut it down to empty the bag, etc., if warm, it was hard to start. I would have to let it cool to get it to restart. This seems have solved the problem.

*by 4***Y on 11 March 2024*

My 1990 model Briggs & Stratton powered Rover Regal lawn mowers magneto final gave up, so replaced it with this unit that superceeds the original. Tested the spark before attempting to start it, gave a really good spark, fitted the spark plug then it started first pull. It even starts easier now than it ever has since I bought the mower brand new, as previously it would always start on the 3rd or 4th pull. Its obvious that Genuine Briggs & Stratton magnetos have improved since 1990. Mind you, nothing else was touched, only the magneto changed.
