So I've been fooling around with ignition stuff in search of a smoother idle. I upgraded the wires to 8mm and added an Pertronix Flamethrower coil. I regapped the Autolite 45's to .040. After maybe 150 miles and much fiddling with timing and carb adjustments and not much success, I pulled the plugs to put the gap back to .035. Wow I say! What happened to the center electrodes? Every one of them has significant erosion/melting. The ends have been rounded, no longer flat.
So, what have I done? Too much spark for these plugs maybe? Is a colder one in order? Or a more exotic platinum type?
Reccomendations?
