Center Squirter problem

[bsprowl]

Recently purchased a Holley Center Squirter R4223 on ebay.  I think I got burned.  After I used carb cleaner on it I found a hole near the bottom of each venturi just above the base plate as these pictures show:





I think all they will do is cause four whistles. 

Opinions and suggestions welcomed.

Can't see the pictures, Bob.  I tried modifying your code but nothing comes up...

Edit:  One fixed...

My center squirters do not have that hole.  Does it go all the way into the venturi?  I think I'd just try to tap the hole and plug it with a 6-32 screw or something.  I don't that would cause you any performance issues...

The holes are probably original. I've seen them many times on certain Holley's. I sold my List 4223 many years ago so can't compare, but my List 4543 850 cfm Center Squirters have them. Don't know the purpose but the engineers must have had a reason. I've never had an issue ( or a whistle ) on any carb with them.

A quick check of my carb collection shows all my 3bbl Holleys have them also.

I've never owned a center squirter, but have seen those holes in other Holleys.  '57 ford 312 list # 1273 has them, as well as some others. Always wondered what they were for. Randy

Thanks everyone.  I found those on my 3 BBL also. 

Now I won't worry about them. 

I sure would like to know: 1) why they are there, 2) how the Holley engineers figured out that such holes would do anything useful and 3) what the airflow looks like as the flow goes from idle to wide open.   Doubt that I ever find out.
