Supposedly with the new reed block fix they are using the WGA9 carb. With that carb you "shouldn't" have to worry about WOT runs. That was the original carb on the 115, which I feel was much easier to tune and had almost no detectable burble when rolling. Now if you have a 3 needle carb no worries, but it does have 3 needles and two needles give some people enough troubles to begin with
Altivillians fixes work extremely well too, I've seen how they perform in the air. I would really like to try one of the BME fixes when they are available.
