I had to make floats for two of those carbs, and it’s really quite easy. Use the old float as a drill guide for the new cork, which you’ll shape down with a file. Once it’s shaped, put about 3-4 coats of super glue on it, even inside of the holes where the screw & rod go. You can clear / re-size the holes with a drill bit, once the glue is dry.

The fine, little springs on the recoil ratchet pawls tend to get wrecked and/or lost. I think that motor has three, like the TD20. You can make new springs with 0.015" music wire, available from hobby & model shops, or possibly your local piano tuner. Make the new springs in-situ, right on the pulley sheaf, using the posts as bending jigs – you’ll need a fine needle-nose to form the small end that clips onto the pawl. They need to be wound tight, but not so tight that they bind up when the pawl is all the way out. If they do, the pawl(s) will rub on the inside of the ratchet gear and ruin it, so leave some extra travel in the springs.
