zenith 32ndx reproduction floats

About in 2023 at least Porsche was selloing reproduction carb floats for the Zenith carburetors (on the 356)

I purchased two at the time for a car that had a intermittant sinking float.

The original float is pictured in Pict1.

a closer view

However when I fitted the new foat onto the original hinge and placed it inti the carburetor, the float became jammed against the wall of the carb.

See pict 2.

A closer view

I believe that the distance from the hinge pin to the crossbar for the floats is too long maybe by about three millimeters.
