hi! nice pictures and information i ll put mines soon! I saw on "chookgb" picture something wrong... I also used the pressure stabilizer and the tube to the exhaust so long and I always had problems and poor performance carburetion on my Novarossi engines. After discussing in forums here in Europe I recommend removing the Stabilizer Pressure and shorten the tube to the 15-17cms and the change was excellent! you should try it.
