The float is a bulb inside the fuel reservoir. The fuel reservoir is the large area to the front of your carb if you have a 1100. If you have a Carter, it is the well-shaped area to the front of the carb. You have to take the top of the carb off to look into it. Sometimes you can just take the top of the fuel reservoir.
You can work the float with your finger or give it puff of compressed air at the needle valve seat and the float hinges. Use one of those cans of compressed air for cleaning computers, NOT your garage compressor. Also, do not work it very hard because it is only activated by the level of fluid in the carb and you can push it out of adjustment (although you probably won't).
