Hot Rods Holley 94 dripping - leaking from nozzle bars - any theory’s welcome…..

Holley 94 carb, ( actually the larger 1&1/16 version from the overhead valve mid ‘50’s cars.
I changed the power valves (2 carbs) and left them over night to check the gaskets were not leaking.
Filled bowls to the step in the bowl.
The power valves were good, no leaking, but half of the fuel siphoned out through the annular/angular nozzle bars. (not sure or correct terminology)
After 2&1/2 days they were down to the fuel just covering the jets.
(Possibly some evaporation involved at this stage)
Question,
Why would the fuel siphon through ?

I also wonder if this is where the fuel drains out after running.

any theory’s welcome !

 

Here’s a parts list (edelbrock) to help with parts id https://static.summitracing.com/global/images/instructions/edl-1154.pdf

 

Thanks, I have a few diagrams, but that is good information.

 

Do you think the fuel level when you filled the bowl would be higher than when in normal use with a float in place? Fuel dripping from those annular nozzle bars would normally indicate an unusually high float level.
I think.
It would probably be worth setting it up to run properly and see what happens then.

Mart.

 

No, but I could measure it to find out.

 

Vintage speed has very good YouTube vids. On one I saw he liked to set the drop different from suggested factory spec. he also recommended 2 1/2 lb pressure on the pump. Might be worth a look. Vintage Speed on you tube

 

Checked and it was where the float level should be, although I wonder if the holes in the bars have gunked up so I might pull them out and check that and try again.

 

yes, I have them all saved to my device, and have started watching them again.
