The cap and rotor are phased to be in optimum alignment with the advance fully in, as would be seen at highway speed. Less gap to jump between rotor and post
Ah, ok then.
I never personally verified if they aligned closest at idle or full throttle.
I guess I just assumed it was at idle and it got farther away as RPM's rose, or was before the terminal at idle and after at WOT and full advance.
So they align closest at WOT then.
Thanks for answering that.
