Lean out and miss fire

A couple have mentioned reversed pickup polarity. LET ME BE CLEAR.

UNLESS YOU ARE RUNNING an electronic timing system such as EFI................

You cannot make it run correctly with reversed polarity because it changes the trigger point (the trigger point fires the spark "then" in relation to the cap contact "tower.". It MUST present the correct relationship

Again this is in reference to a distributor WITHOUT electronic timing control, Even one that is locked out.
