Hi. We use a pertronix 3 system on 67 318 in a 74 dart sport. Timing is ok at idle checked via timing light. When revving the engine , the rev light goes out , and the engine suddenly stops . After a half second or so, the engine sparks again, with a healthy timing idle. We know it has to be spark plugs losing power, since the timing light goes off when revving. Also , we by passed all wires and connected the ignition coil directly to the battery. Healthy idle but same problem as above when revving. We cleaned all the points on the distributor, so it should be grounded. We think it is the distributor that has the problem. Any thoughts. My dad thinks it might fix the problem is we pull out the spring on the inside of the distributor higher. Please help. I get (hopefully) my permit in less than two weeks so we need it to be ready to go
