.I had a btch of a time finding bleeds today,
Thats why I just solder up and re-drill re-size my own.
On the stock Holley 4779 carb body what are the sizes of the air bleeds?
Useing a narrow band type (heated) 02 sensor and Summit/Autometer gauge
(you can also read the Narrow band 02 sensor's output with a digital volt-ohm meter)
