    SOMETHING AMAZING HAPPENED. I truly cant believe I'm saying this... but we got it to somewhat work!!!! I'll post most details later, but via the Arduino, some VERY simple code (literally digitalRead the sensor, digitalWrite to ignite the spark), and a lot of denial (trial) and error, and we have liftoff!

    Now, this was only one cylinder, and the advance was hard set manually to about 7º or 8º BTDC. Ill have to post some pictures and code and wiring diagrams. All will come! But it was responding to throttle input with the starter NOT being engaged. Admittedly, super choppy, on one cylinder, and poorly at best, but it was definitely sparking and completing the 4 cycles for a solid 4-5 seconds. This is super exciting!

    Stay tuned!
