Loose booster on 4500 Holley

[markdunlap]

I just noticed that one of my boosters is loose on my 9375 HP 4500 carb.

What is the proper way to repair this?

I know there are booster pins and even know where there are some pins, just don't know about fix.

Try a 5/16 center punch, or a brass drift to set the booster pin tighter.
