<VV> Re: Them dern sparky plugs

[Lew Rishel]

Seems ta me I remembers frum e-lec-tricty class years ago,  perfesser Edison
(or wuz it Tesla) said, high voltage takes the path of least resistance.
That would be the closest distance between the two electrodes. And also,
each time a plug fires, a tiny bit of metal is evaporated from that spot.
Then the next spark exits from a different (closer) place and another tiny
bit is gone. Repeat and repeat and repeat. Eventually, as some of you more
observant types may have noticed, the plug electrodes are eaten up, the gap
is oversized and the dern car wont hardly run. So, this makes a good case
for multiple ground electrodes, dont it ?? Again some of you more observant
types may have noticed that the US military airplane piston type engines
have used multiple (platinum) ground plugs since WW II , I know, I hev
changed many of them.
The split fire plugs on the market present a form of this multiplicity,
(sorry about thu big word, Hanky-poo) and, you can do this on your own
prefered brand. Just bend the ground electrode back somewhat, and with a
fine jewelers saw blade, make a lengthwise cut in it. Then re-gap as usual.
This  will allow you four surface edges on the ground electrode for
discharge instead of the usual two, so the gap setting will last longer.
Alternatively, if you do want some multiple electrode plugs, I have several
new sets for sale.
