the trigger wheels on CIS/digifant has 4 trigger "holes" so that the hall
sender pulses for each cylinder

the hall sender on ABA distributor isn't used for the same purpose, it's a cam
position sensor which only triggers for cylinder no.1 (1 hole instead of 4)...
so if the trigger wheel wasn't swapped, you'd only get spark for cylinder
no.1.
