I read this with interest, and just the last few posts my light bulb started flickering a little brighter. You said you could use a flat headed screwdriver in the ignition and it worked, my question, what is on the tumbler assembly that is supposed to 'interface' with the ignition assembly, that looks or acts like that screwdriver blade? I don't have (and never did) an ignition assembly apart in my hand, but if the screwdriver blade works then some sort of interface must either be missing, or not being inserted deep enough to interlock. Or, am I just burning out my light bulb again?
