Hi guys, I now have an all metal 15Hp carby in reasonable condition but what I didn't expect is the orifice size says '45' on it. When i look on parts here, the 45 is for 9.9hp and the 15hp takes the 56 orifice size. On this 15hp the plug screws to the side of the shaft leading to the carby throat and not on the top. Strange as if you look at pics of this 15hp alongside a 9.9hp (15hp is top one with better condition bowl), it must be a 15hp carby going by the inner throat diameter. Anyone with experience with these have any thoughts on why? Cheers
