Always use the spark plugs designed for the engine. You see the
electrode is at different lengths to place the initial combustion
ignition at a point, otherwise the explosion will bounce all over the
place, burning holes in the piston along with an annoying ping. And I
think I would use the same .025" gap, but use the heavier wires.
Remember not to touch them with oily fingers, whatever they use devolves
in it.
