I recently bought this for my son so he could see how we have been gapping spark plugs for years! It was the same one my dad bought for me and one I hope my son will pass on to his son if we still use the internal combustion as it is today.
This is a simple tool that with a little knowlege can make or break an engine tune up! I have seen many people tap their plegs on the ground or use a screwdriver to open the gap and so on! I gave simple instructions on how to determine the correct gap and how to use the tool and turned him loose on the riding mower and, voila! Runs better than it ever did before!
This tool is so easy to use. It makes checking my spark plugs a snap.
Nice little thing
I only purchased this item because it was Craftsman and made in the USA! Great product to have in your garage or in the car. USA made quality!
