And a size chart:
Model /CFM Venturi Diameter/ Bore Diameter
primary secondary / primary secondary
4Jet/486,1-1/8,1-1/4/1-7/16,1-7/16
4Jet/553,1-1/8,1-15/32/1-7/16,1-11/16
4Jet/692,1-1/8,1-15/32/1-9/16,1-11/16
To further muddy the water, the Packard Service Manual in the "Specifications - Fuel System" for 5560 & 5580 lists:
4GC/CFM?,1-1/16,1/1-5/16,1-5/16
In a document I have from "Texas Region, Packards Intl" for the the 5588 2x4:
4GC/CFM?/1-1/64,57/64/1-5/16,1-5/16
I have in my notes (but no source ref) that the 5680 is:
4GC/CFM?/1-1/4,1-1/4,/?,?
