How is this spark plug tool tester used? Thanks.

Gap gauge right, gap adjustment bottom and stabbing thing left. Good luck.

Thanks. Any idea how to use the top part with the lightning bolt and sensor?

Looks like a neon bulb there to check for spark at the plug wire. Put the sensor up against the plug wire while holding the metal portion in your hand to provide a ground for the neon.
More compact, pen size versions*of this were common long ago when engines had spark plug leads.
I need a gapper this bulky like a hole in the head. Gimmick tool with little to no practical usefulness.

Oh ok. I see now. It's used like how you would put the clamp end on a spark plug wire to check the timing, but you just touch this up to the wire. Thanks.

No sure don't. Is that a little light bulb in the middle?
Is that some sort of light bulb in the middle? If so, the long dagger would reach the contact in the wire or boot.

I have one of these...somewhere. Haven't seen it in ages. Haven't used it in decades. Mostly worthless.
