What kind of mods would you think should be done? I run the stock OS 9B on my scales, they seem to work fine as is

Glen, what engine are you putting the carb on? I put one on a Picco 67EXR for my scale boat and the only thing i had to do was elongate the mounting holes on the carb just a little...its bone stock internally and i ABSOLUTLY LOVE IT! Rick would know for sure, but i think it will bolt right on a CMB 67 Green head with no mods at all.....i think!

It is a bolt on. I do not think people mod them as they work well as is. Someone was using the factory reducer to run them on .45 motors.
