A couple of weeks ago I placed a large order with VB, and they were able to
fill 25 out of the 26 items on my list. The one item they did not have was
the Grose Jet. They told me it is not being manufactured anymore. I have
since heard this from another vender. Has anyone else had this experience?

Glenn,
Have you looked for vacuum leaks
A) caused by loose vacuum line 'elbows'
or
B) the o-ring inside the needle adjusting screw?
These two things made MAJOR mixture differences on my car.
Have you tried both the Grose-Jet and the regular needle &
seat on the
floats? Is the float pivot pin in good shape? What is the
manifold vaccuum
at idle?
