New from Fujiwara is this high performance big bore Venturi carburetor for the Zenoah G320RC and G320PUM engines. This carb is based on a carburetor equivalent to the Walbro WT-1107 used in the G320 series engines, but with an increased 14mm venturi diameter to further enhance the engine's potential. The design of this carb is to provide smoother acceleration and more powerful revving, especially in the mid-to-high RPM range. This carb comes as shown with the carb and gasket.
