AND I read in a old mag that you can add a 12 volt flash lite batt=20
and power the coil from that wile spinning the starter and car/truck
will start better=20
i was thinking of adding a chevy vaga oil press switch go from one to
butt i'm not driving a car/truck with ponts any more =20
and if i keep it tuned up I dont need it any way=20
sorry to bore you =20
