Title: Some already know

But, basic troubleshooting tips, heh, review,
And, if you suspect fuel, it's good to have Berrymans spray around. Or ether,
Just be careful about too much,

Note: as a former auto technician, I do not recommend those goofy 4 ground spark plugs seen in that post
I saw too many cars that ran like crap with them
9 out of 10 if your car or bike is stock or near stock it'll run better with what the manufacturer put in it (possible exception for iridium from the same spark plug maker, I reserve judgement there)

You add more electrodes for a larger spark but then you block the spark by having too many electrodes in the way. Makes perfect sense!

I'll stick to single electrode plugs and just clock them correctly. Never had a problem with one yet.

I'm too lazy to even clock them
I did it on a car once, and no seat of the pants difference I could feel, So I never bothered after that

Yeah, I can't tell a difference either but it makes me feel good about it.

Just cause i'm lazy, don't mean you gotta be

I don't believe the extra electrodes make for more or even bigger sparks.  Electricity chooses the path of least resistance, and adding a spark plug with more electrodes doesn't change the power available from the coil or other parts of the ignition system.......so I believe the spark plug still only makes one spark regardless of the number of electrodes on the spark plug.  The spark goes to which ever electrode happens to have the least resistance.

You add more electrodes as a marketing gimmick
The spark probably is now somewhat 'shielded' from the air / fuel mix, which may explain why some cars run worse with those plugs installed

Multiple electrode spark plugs were popular 1900-1925.

They've been around that long?

Just found this on a Model T forum. It spins the flame!

The constant whirring sound would drive me crazy! :o

They tried everything. Wait 'till the spinny thing all got sticky from carbon and half combusted fuel and oil.

I'll bet that was Expensive..  Look at the work to make it.. Weren't no CNC machines back then.
Looks like gapping that thing mighta been a task.

That's the first thing I thought.
