Re: Rotor gap to distributor body terminals
The rotor gap is critical in setting the peak voltage the coil will reach before discharging. Too small of a gap (less than 0.025") will result in more spark plug misfires during idle and at W.O.T. The bigger the gap, the higher the coil voltage before discharge to the plug.
Those gizmos sold in the 60's-70's at auto shows that fit on top of your dizzy cap to fire fouled plugs simply added an additional gap to raise the peak voltage before coil discharge.
