Mike: Starting backwards. My .75 AX starts up backwards about 50% of the time. I usually just tap the throttle and it goes the right way.. but it does start up backwards very often. I tend to tap the prop with the chicken stick in the reverse direction, but never to the point where it goes beyond compression, I usually let the compression push it back forward and it starts up, first flip every time.. however, often backwards.

Would that be the low end mixture again??
