Ray, I was testing the new timer board with my original ignitions with the toroid transformer on it and ran into a snag. There must be a resistor value change or the inverted signal from the optocoupler output will not fire the ignition. If you have the schematic and can re-post it, I will tell you which resistor number it is. I can't seem to find the combo board schematic with the problem resistor. It all boils down to the positive bias with too low of a resistor value. It's a 150 ohm I believe shown in the schematic. This must be changed to a 680 ohm to correct the situation.
