How to adjust floats?
 

Hey Guys,

I have been told by several now that I need to adjust the floats on my new Holley 4175 (4 bbl Quadrajet replacement). I've looked around, but I can not seem to find where or how to adjust my floats? Is there a screw I have to adjust like with idle speed, or do I have to open the carb up & slightly bend the arm the float sits on?

Thanks,

John

Here is a link to an exploded diagram of my carb.

On the spreadbore (4175) you'll need to remove the float bowl and set the float height to spec by slightly bending the float arm. Here's the link to Holley explaining all the adjustments neccessary.
