Scott-
Check to see if there is any excessive wear between the float and the pin.
Check to see if the floats have any air leaks. Shake to listen for fuel inside and immerse in fuel to check for air bubbles. This is no good of course.
The float height is set at 8mm. Weber quote several heights for different models but 8mm is average and acceptable and always useable. The height is measured with the gasket in place. The
needles have a spring loaded ball which means the needle will seal its seat but the float will keep moving. The float level is measured when the needle just contacts the seat. This is
measured with the carb top held on its side and the float facing up. If the top is tilted the needle will be seen to move out from the seated position. If the top is slowely tilted back
the needle will move in towards the seat and when it stops moving this is the point at which the distance between float and gasket is measured. Adjustment is achieved by twisting the brass
arms using long nose pliers. The droop setting is 15mm and is the distance the float droops when the top is held in what would be its installed position eg horizontal. This is controlled
by the tab at the back of the float . The float stops drooping whent he tab touches the back of the seat. This tab can be bent with pliers.
As I said if you've pulled a normal carby apart its basically the same.
