Buy a rebuild kit from Napa. Echelon. They sell the float separate, be sure to buy a brass float.
Take your time, have a clean bench and take pictures as you go with your phone to help remember what goes where and how the linkage goes.
I was gonna have mine rebuilt at carburetor land in Hawaiian Gardens but when I walked in the shop seemed disarray so I attempted it myself. In doing so I learned that I had too much fuel pressure and solved another problem at the same time. Plus, its easier to get acquainted with it on the bench so when you're on the water you won't have to call vessel assist if something goes haywire.
Your float might look something like this fuel logged, sunken neoprene one so good idea to have a look. Its only a few bolts and machine screws to get it apart.
