OK did a little bit of playing today per the advice of some gurus. I played with the Zero Crossing pot, and with the different edge triggering options. See pics below.

- Zoom to see where the cam trigger falls in comparison to the crank triggers. Ideally it should fall exactly between two of the crank pulses. I played with the different edge options. This pic shows the best combination I could get which is Falling Falling.
So the cam signal is much better now. But I'm still having the same problem. The cam pulse appears to be as steady as can be, so the crank signal has to be the cause of all this. Will continue this battle this weekend and hopefully get this thing working!!
