An experienced ear could tell me immediately that I'm running to rich or lean or how the advance should change, but I'm still doing a lot of guessing with the "poke it and see what happens" technique. Do you have any tricks of what to look for when tuning the ignition advance? Since the timing is not dependant on MAP or TPS or RPM I would just take the prop off and set the advance at say 22 or 24 degrees right up to 6,500 RPM. Later if you want max cruise mileage or to reduce popping on decent, you can map real large amounts of advance for closed throttle higher (off idle) RPM. If I watched that video a few more times I might get a clue as to how its done. Lynn E.
