ORIGINAL: Tired Old Man
I was referring to the original relaease of the 115 where the carb was a bit too much (wb 25) and the reed bank design needed some work. The current arrangement on the 115 seems to be working out just fine.
I assumes you were, they are now using the wga-7/9 which is responding very well. The wb-25 was calibrated for around 140-16cc, and is going on my 150cc engine,for sure.
