I am having a problem keeping my 1960 invicta running, it has ran for 1 minute a couple of times. this model has the throttle start, I am wondering if this is part of the problem. I was also wondering how that starting system works? Does it sense (RPM) that the motor is running? Does it do this through a relay? I am initially thinking that the ingition is cutting out, maybe a fault somewhere in that starting system. thanks

I finally found the issue, it was a faulty harmonic balancer. turns out this is a common issue on the old nailheads and some old cadillacs. since everything is based on the timing marks on the balancer nothing was right. The rubber dry rotted and the outer ring which has the timing marks on it rotated. I had the balancer rebuilt and she fired right up. I hope this helps someone else out there.

try a jumpper wire from thr+ side of battery to ign side of coil for a test will show if there is a problem with ign switch or wires .your car has a wire from starter to coil that connects when starter is engaged,otherwise it goes through ign switch. .Believe but cannot say for sure that vacum disconnects starter.
