Ok, I'll bite (ignition pun), how do you have 4 spark plug wires coming off the distributor going into the copper pipe and magically have 8 coming out of the pipe going to spark plugs?
I know it's a 4-cylinder.Hey 42,
Simple.
That is a 4 cylinder engine, equipped with "Dual Plug Heads".
The wires are "spliced" in the tube..

My ultralight had 2 sparkplugs in one cylinder.Doesn't make any sense.
I know it's a 4-cylinder.
That's what had me scratching my head (pun).
If both plugs are connected to the same wire:
It will only fire the plug with the closest gap, and if either plug shorts (like the one that never fires) neither one will fire.
Doesn't make any sense.
The only way it would make sense is if they had horrible electrode wear, it would have 2 plugs to wear out before it stopped firing.
