Mounted on NGH 35 cc with WT series Walbro carb. Choke clears when mounted. Throat diameter 19 mm. Bottom 3 mm of throat is beveled out to 22 mm, (so choke will clear I presume). Height 23 mm. Outside diameter of intake horn 35 mm . Mounting hole spacing center to center 33 mm. No performance data as engine has never run without it.
Did I get it all?
