Mikuni mx40, dish spring?

[Kristian]

As mentioned in my previous post im putting my mikuni mx40 back together, But for the life of me cant remmember which way the "disc spring" sits under the glowplug boss.

If the boss is held upright, does the narrow part of the disc spring go up to the bottom first or the wider part??????

As you can tell its concave depending on which way its faceing, narrow top or wider bit first to the plug boss base???
