i have a 95ax and the first couple of flights ended in deadstick when opening to full throttle as well. Keep it set slightly on the rich side on the high end and use an OSF plug. The #8 plug was not hot enough. Also do a bench test with WOT and hold the plane in different roll and pitch variations (nose up and down) to make sure it doesn't die on you before flying. I do this before my first flight EVERY time I go to the field. After you have a gallon or two through this engine, you'll LOVE it.
