Default O.S. Outboard Carb Fit on a K&B???

I'm converting an old K&B 3.5 inboard that came with an exhaust throttle to a carb. I'd like to use an O.S. carb because they are known to work quite well. I thought I read on this site that the carb off an O.S. outboard would fit. Anyone know if it will?

Thanks.

WELL THE OS CARB IS A #20J ITHAS A 10MM BORE AND THE OD IS 15MM WITH A BRASS SLEEVE, THE SLEEVE MAY BE REMOVED MOST LIKELY BUT IT'S NOT VERY THICK , THAT CARB IS 76 BUCKS FROM TOWER.

Also mecoa spec says the k&b carb has a .437 dia base and the os is .590 so it doesnt look good on paper for an os21 carb to fit a k&b engine but Ido not know how thick that brass sleave is and if it is removable ............. Ron, Jerry??????????????
