Slant 6 engine ignition timing stays retarded.

Might have to pull the distribtor and rotate it one tooth. Also, there is a second adjustment slot on the back side of the distribtor.

I'll look for that second slot though I can't imagine what it would look like. Can you be more specific? I've had this dist out many times in the last several months and don't remember seeing something like that.
