Was having trouble with my carb---turns out one of the floats must have a very tiny hole in it, because I could hear fuel inside when I shake it. I have been drying it out for a couple of days. Almost dry now. Question: What is best sealer for the float?

Your best bet is to solder the hole if you can identify it.

If you hold the float in your hand it will warm it enough to force the gas inside out the hole if the hole is on the bottom. I don't mean the actual bottom of the float but the part that is down as you hold it. You should see the liquid come out and cover the outside of the float. If you can't find the hole then put the float in warm water and note where the air bubbles come from. Or put the float in the refrigerator or freezer and cool it down. As I warms in room temperature water it will expel air from the hole or split.

If you decide to solder it only use a soldering iron and never a flame. Also use a low melting point solder and only the bare minimal amount to cover the hole. Be sure to clean the area well, use a good flux and only apply enough heat to just melt the solder. It may take a few short applications of heat to get the job done. Test for leaks with one of the above techniques. If no leaks you are done.
