Look on bowl side. What numbers/letters are on left? What dimensions are cast on back of bowl casting? There are several gnerations of "94", some of then not even 94.
I think AA-1 is upside down V nozzle bars, 2100 is single direction slanted bars. Both 1 11/16, secondary venturi on bars is 2110, 1 15/32...the earies at least like float a bit lower than spec.
