Hi Dave, Yes, I'm guessing the Mac carb is a diff size than a CMB? Not sure so if anyone knows it would be good to know.
Thanks,
Chris

Hi Julian, That looks like what I'm trying to piece together. Did you just bolt on the backplates or were timing / other changes required?
Thanks,
Chris

no changes required straight bolt On and go. But you will the angle slowed intake and oring, carb with oring, drum in order to make it work. If you look at my flywheels I cut them down a bit. You will also need the drawbar to keep the carb in place.
