Review on Good Vibrations 140 Doctor Tune Up by Ricardo Ware

It's fall again - it's almost time to pack away your mower and winterize your snow thrower. I looked for my trusty spark plug gauge but it was nowhere to be found. So on a whim I ordered this. Actually works better than I expected. It has keys for all three standard spark plug sizes - 3/4", 13/16" and 5/8", but you must be careful not to damage the insulator when using it. There is also one in the picture small file, handy for dressing the electrode. Finally, there is a tool for adjusting the gap and a tool for measuring the gap. This is not something you want to use every day, but the quality is good enough for occasional use. Overall I was very happy with it.The best part is that everything folds up easily into one big swiss army knife style tool.Very easy to find in the tool box and individual tools don't get lost.
