64 Elco with a (suspected) 69 305ci. Getting at best about 2 seconds of crank then nothing. Usually just get a click, sometimes nothing. Maybe 1 out of 50 tries it will start. Replaced starter, solenoid, positive battery cable, alternator (probably unrelated). Battery good and have been keeping it charged. Have new ignition switch ordered. Beyond that, I can't think of what else to check. Really hoping the ignition switch does the trick, but if not... any suggestions?
