I disagree. The float level is nowhere near as critical as the jet level.
This is because the important part of the jet is the size of the effective
opening, which is set by how far the needle goes into the jet. A 1/16"
(.0625") change in fuel level will require less than .001" jet movement to
compensate. Which is good, because the floats don't control the level all that
accurate anyway <g>
Another way to look at it is that the carburetor venturi suction is much more
than 1/16" of gasoline.
