Hi,

I have this Holley carb on my 1956 International harvester S120.

I have looked through all carb information I can and even took it to a local shop but no-one seems to know what the small T adjuster on the front of the carb does - arrowed in red.

Inside it has a long needle so I am not sure if it is a drain plug.

The idle adjustment screw is on the back and is not this.

Any ideas?

Thanks,

Lee
