Post subject:  MR 175 CARBURETOR SWAP

Can anyone tell me if a 1974 CR250 carburetor will work on my 1975 MR175? I have a rough candidate for rebuild, but I'm determined to do it no matter what. The problem is I don't have a carburetor, at all, to compare to. Any info would be greatly appreciated.
THANKS

The CR250 carb is too big to fit in the openings where the MR175 carb went. I would try a 32mm Mikuni which should fit better where the 28mm keihin was. If the keihin is in good shape I would keep it since it is just about the ideal size for that motor.
