i know if it ain't broke don't try to fix it...i have a 91 trail boss that just had the top end rebuilt and it has been running fine accept for a hard time idleing. it had a toggle switch installed where the ignition was. i was trying to install an autozone special ignition with a key. i realize that it was for a car, but i didn't want anyone to just be able to hop on and take off. it started fine after the install but i turned the switch off and it stayed running so i turned the switch to acc. and it died. no more spark?????? any suggestions
