Basically, you put everything back together in the reverse order of the teardown. All worn or damaged parts should be replaced. All replacement parts that come in the carb kit should be used as appropriate.
Upon completing the assembly, the accelerator pump arm should be adjusted so that it has 8mm of travel.
The float should be adjusted so that when it is inverted and resting on the needle (with its own weight) the distance between the float and the surface of the air horn is 4.1mm. Even though this photo makes it look like the bottom of the float is like at 9mm - it is just the angle at which the photo was taken.
The float should also be adjusted so that when t is right side up, there is a 1mm gap between the float and the needle.
