Six pack carb hi speed air bleed diameter

Hi again. Can someone point me to where I can find the carb specs for the six pack carbs? I'm looking for the air bleed specs.

Which carb number and is it a replacement or original? I have 17 Six Pack carbs. I bought 2 sets of gauge pins and have pined all of my carbs. There is a variation from original and replacement carbs. The pins are not that expensive if all you want to measure is air bleeds the small set would cover that up to .060. That being said the outboard carbs varied from .027 for replacement to .039 for original HSB .052 and .068 for IAB. The center carbs measured .026 to .028 HSB and .065 TO .073 IAB.

Hope this helps

Thanks, that's very helpful. I'm building a six pack setup with mechanical secondaries. The info is to help me understand how the original system functioned. I have the 2300s and had completely closed the outboard idle screws. I'm getting fuel pullover from the primary carb. I have rebuilt the carb AGAIN. As was as rebuilt the outboards. I have swapped the carbs around since they are all 350 cfm. Same issue with all carbs. I suspected the hi speed bleeds,and while they need work, I now believe I created the problem by forcing all idle air through the center carb.

Try using all three carbs like their intended to be run, use the idle circuits on all of them
The stock tri Power Mopar, Chevy and Fords did
I've ran and tuned more than one stock 440 and 340 motors with them, I had to use the outboard idle circuits to get them to run good

It's better now but one carb is dumping fuel out the air bleeds and boosters. I moved the carb and the problem follows the carb. I tested the power valve and the diaphragm hold vacuum. I replaced the float and seat even tried a diff metering block. Same problem.

Rule number one on how to make more power, fix what is broken first before anything else
Figure out what is causing that crab problem and fix it or replace it with a good carb.
Six packs rule, when tuned properly

After another disassembly I found a wasp nest in the vent tube. I hope the blocked vent tube was causing the fuel to flow out the air bleeds and boosters. Need to get a throttle body gasket and try it again. One last time and this 2300 is headed for the trash bin!

Just to close this thread out the wasp nest in the vent tube was causing the holley 2300 to dump fuel out the air bleeds and the boosters..

Thanks for letting us know, that will help others on here later.
Dedication and thorough methods get great results, huh
