I wonder why they took so long to get to the air-vane idea, i like the G3 carby (there second, and last vane carby) but with others doing it that way for so long, and with mechanical govenors also aroung, i wonder why they took so long to get around to it (must have been 68 or 69 the G2 came out)
The automatic makes a beautiful collectors peice due to its rarity, but I am guessing that rarity comes down to it's popularity, or therfore lack of!
