Carb Floats Hang Down Uneven

No, not a problem.  What counts is the position of the float when the tang just touches the end of the float valve.

Actually this is a problem. If the float arms are bent, in a way the tang needs to be bent at a extreme acute angle then it will apply sideways pressure on the float needle, possibly bypassing the spring load of the pin, and could cause an over fueling condition. Best to pull all the floats. Align the arms attaching the float (brass or plastic) at a 90° position when viewed from the side. Visualize the float side as clock face and the arm should intersect the float at either 9 O’clock or 3 O’clock respectively. Also check the float arms across for flatness. Across in this case would be from #1 toward #4 bodies. Mount the carbs as if on the bike, hang the floats and use a straight edge across the bottom of the floats to test they are all hanging equally. If a pair needs adjustment the maximum travel down tang may need to be adjusted to raise or lower the pair. If one float of a pair is off the straightness of the float arms should be trued. I always try my best to return all float arms and tangs to the flat position, and then adjust fuel service levels using the clear tube method.
