No worries. Some Holley 5200/G180 carbs have only a primary idle system, while others have both primary and secondary idle system.

The jets and tube part numbers do not correspond to Weber part numbers.

Go to the library and get this book: "Holley Carburetor Systems 5200 Series" by Mike Urich, HPBooks. Or just $8 from Amazon.com

it would seem like you want a jet in the secondary.

mmm

i have a holley 180 and looking at setting it up on a a14...

ive done a bit of searching around but all i could find is the recomended settings for 32/36 webers.

my holley currently has
pri/sec
main jets: 135/135
venturi 4.0/4.0
emulsion tubes 16/16 (not sure how numbers correspoend to weber sizes ?)
air correction 195/195
idle jet 60 (only has on in primary, is there a reason blank hole in sec??)
power valve 14
