Review on 🔍 ABN Inline Spark Plug Tester – Straight Boot Ignition Test Light for Small Engine Vehicles: Cars, Motorcycles, Lawn Mowers, Chainsaws by David Elam

I took this to review the problems I had with the bike. This worked great (although spark didn't become an issue). Since then I've also used it on some of my old cars that I've repaired and this is where it helped the most as I had an issue with a cylinder that would only not work at higher RPM. This allowed me to identify the cylinder and get to the bottom of the exact cause.
