Re: Carb Kit for 1950 Evinrude 7.5 Model#4434
It is a MD by Tillotson. You probably won't find a kit for it. In fact, when they did make kits, they were major kits that included dang near anything in it that was replaceable. If it's any help, the MD was an extremely popular carburetor in those days, used on a gazillion different makes and models of motors, with variations to suit the applications. I'm amazed that nobody makes aftermarket stuff for them.
