Not very long at all....we just estimated that it was advanced about 25 degrees too high. It was never ran down the track like that. But here's where I stand now. I'm attaching a pic of the timing pointer for starters. See, when my engine builder timed the engine, he used the half-circle as a reference (See "A"). When I brought her to the other guy, he could tell that it was too far advanced and that we used the half circle as a reference point. He then told me that I needed to use the top of the pointer as reference point. I just checked the timing (set the dial to 10 degrees) and the black mark on my harmonic balancer appeared at the spot I marked (See the "B" above the "A"). What's that mean? Is the timing retarded?
