Single Main Air Bleed Carbs

(1/1)

Malibu72:
Can Single main air bleeds be reduced in size just like the large main air bleeds in the 75-78 Chevy Qjets, allowing the use of your custom rod and jet package?

Cliff Ruggles:
They use a longer "nozzle" as a restriction which extends into the incoming air stream.  They are best tuned with the later "M" series metering rods with the .036" tips. 

I have set some up with much smaller jets and .026" metering rods, but I prefer to tune them with larger jets and "M" series rods.....Cliff
