I'm having a bit of a problem. I'm using the Autolite 4100 480cfm carb that came with my car. I have some experience working on carbs but mostly motorcycle carbs. So I started researching and checking out my 4100 today to see what problems I might run into and found I'm missing something. Pardon my ignorance, but what is the name of this part?

I know what it does but I don't know what I should search for. Where could I find another one? I also have a 600cfm 4100 carb that came with my car would they transfer over or are they specific to the type? Thanks

Booster venturis. They vary depending on carb size and engine application, just like main jets.

Is there a place to buy one or will I need to find an old carb to get it from? If I have to find an old carb can it just be from a 480cfm model or does it have to be from a 480cfm model off a Mustang not a Galaxy?

Any 4V should have one that wil 'fit', whether it will be the right meter size is another story. I've never tried it, but a primary set might even fit. Calibration will be your issue. The Factory Service Manual lists them by application.

I used the junky caliper I have at home and measured the main hole diameter of the venturi on both the 600cfm and the 480cfm. I found the 600cfm has a diameter of .542" and the 480 has a diameter of .535". Looks like I will be looking for another 480cfm 4100 for parts. Any one have one lying around?

The Qwik shot would be to contact Pony Carbs.
Good Luck!
