I need to do some tuning with my distributor and need some help. At the moment my initial is 12* and total is 34*. I am sure it needs around 18* initial but I have some weird going on I need to figure out first. When I rev the engine and it gets to the 34* total, if I rev it on up the timing will fade. My balancer goes to 50*. I see nothing after the 34*, all the numbers disappear. Could my timing light not be working with the MSD at that point?
