This instrumentation is somewhere below "Colortune" and somewhere
above "spitting on the manifold". Anyone remember a method of
using a NE2 neon bulb with one lead wrapped a few times around
a sparkplug wire. The story goes that you made a bank of 4, 6
or 8 bulbs, depending on the number of sparkplugs, and by looking
at these bulbs you could see which sparkplugs were weak. I always
wanted to try this but never got around to it. It doesn't give
any information about the fuel mixture, just the sparkplug.
