I bought a 70 model wit a supposedly rebuilt carb. yeah right this carb was shot. i picked up a 22 mm unit on eba for like $35 with shipping it had the petcock mattached so no adding ys to the line.
I threwit on and wasnt happy with the response so i raised the needle two notches and yahoo it ran great started easy idles great. i bought the ct110 carb to ac connector from the Dr and im running the stock air cleaner so once the project is complete deep water crossing should be effortless. i really went with the 22mm becase im going to do big bore and cam but it works much better than the 19mm did on a stock motor.   noticable power increase over the stock carb and the new 19mm utilizinng the same air cleaner and manifold. i had my doubts about the manifold but i suspect the 110 used the same manifold.
