Guys, I got a bit of advice from OS today. You can retard the timing just a bit by adjusting the sensor 1mm counter-clockwise (viewed facing the prop hub face). This should improve hand starting. As has already been mentioned, about 1/8 or a little less throttle is also the best throttle position for starting.

O.S. is extremely safety conscience. This is one of the reasons for having the CDI not fire until a certain rpm is seen.
