Paul,
The notches on the side of that spark plug tool are just wide enough to fit
the sidwire.
You simply give it a twist of your wrist to move the sidewire closer or
further from the electrode tip. At least, this has always been my
understanding. For lots of great information about sparkplugs, check out:
