I did have problems with my Posa. I still am not always happy. My problem was that my prop was to much pitch and when the throttle was fully opened, I didn't turn up enough rpm to use up the free flowing fuel that entered the carb. Once I reduced the pitch of my prop, I turned up the rpms enough that rpm more matched the flow of the fuel. I actually would run so rich at high throttle that my eng. wouldn't keep me in the air. Just thought I would throw this in. It may not have anything to do with your problem.
