Review on Champion RJ19LM 868 Copper Replacement by Andrew Walton

I bought this for an Ariens snow thrower with a Tecumseh Snow King engine. It's about 8 years old and I've never changed a spark plug. This replacement works perfectly. It sits in place at the top of the cylinder in the combustion chamber, waiting to spark and ignite the air-fuel mixture. When it does, it works flawlessly and creates the perfect spark that ignites. The explosion then pushes the piston back into the cylinder, transferring power to the wings and drive mechanism. It never stops bubbling and has no problems waiting. What more can you ask for in a spark plug? He has a function in life, and he carries it out proudly and unselfishly.
