Mark,

The open elevation of the E/B key piece and pad cup is determined by
cork under the left hand E/B lever (where the lever rests against the
body of the clarinet) and, if the left hand lever is stepped rather than
being a finger going into a hole, by a thin piece of cork, either on the
top of the lever or on the underside of the overriding arm that comes
off the E/B key to the left side of the clarinet. There should be no
play between the left hand lever and the overriding arm when the left
hand lever is actuated.

Take off both of the left hand levers and see if the cork on the
underside of L.H. E/B lever is missing. It is hard to see this cork when
both keys are on the clarinet. While the keys are off, also check to see
if there is a 1/32" or 1/64" cork on the bottom side of the overriding arm.

When properly set up with correct cork thicknesses, the E/B key spatula
will be on the same plane as the R.H. F#/C# key and the bottom, flat
side of the E/B key will be barely touching the crow foot.

The outer left hand lever, the L.H. F#/C# lever needs to have just a
skosh of play between the lever and its overriding arm. Otherwise, the
closed F#/C# key will not be allowed to close fully. The amount of play
should be very slight, but perceivable.
