blown 440 timing help...

If you are using an msd ignition, i would NEVER trust, or believe, a dial back light. And i dont trust them much, even without an msd.
Use a timing tape, after making sure of rotor orientation at a confirmed tdc mark.
Or, if you think you will have trouble with the tape, tell us the diameter of your balancer, and what you want total timing to be, we can tell you where to scribe the total timing mark.
