Carburetor 1960 Holley Primary, Secondary

Which of the metering jets on a Holley 4100 are larger, primary or secondary. Did not take note when disassembling.

maybe I'm confused but a 4100 carb is a ford/autolite, not a holley. on my '59 ford 4100 the primary jets are 65 and secondary are 54, o primaries are larger.

i texted mikes carbs, they said the primary jets are small than the secondary jets. my mistake. when i rebuilt my 59 carb the primaries were larger when i took them out.

Thank you! I looked closer and found both sets were the same size, just looked different on the bottom. Two were recessed on the bottom side and two were not. Both, however, were .58
