After the airplane was returned to me, my gut was telling me something was wrong. Some of the work was, in short, a bit sloppy. I took this as a sign to go over everything, including 10 hours of high-speed taxi tests before the first flight, but clearly it wasn't enough. I recall looking at the throttle and how unprofessional it looked, in particular, "full throttle" on the right side only opened the throttle to 75 percent. The left seat throttle lever opened and closed the carbs fully, so I decided I could live with it.
