Re: is a fleetwin 1954 carburator kit fit a 1953 fleetwin
Yea, like Chinewalker said, the '53 and older Fleetwin uses a Tillotson carb and parts will be a bit tougher to find. You can try Sea-Way Marine or Engine Blade and Prop. It seems like these two places have the best supply for older motors. The Tillotson carb on your motor looks very similar to the later style, but not quite the same. Oddly enough, the mounting is 90 degrees off and the low speed jet is opposite. I think you can get by with your original needle and seat, if you can't find one, but you'll want a new bowl gasket.
