Holley 2bbl carb question

[Yellowbird77]

I recently bought a Holley 8993 carb to replace my old Rochester 2GC on a 1977 3.8L v6. I think it may be missing a piece however. I've attached a pic of the carb and circled the area that looks like it's missing a cover or something. Anyone know if that's correct the way it is, or what I'll need to get for it if it is missing a part(s)? Thanks for any help!

Hey, thats kind of funny. I just made a post to an old topic that covered this same question. The post should show up at the beginning of this discussion.
Good luck, Mark

Oh Yeah. Do you know what size main jets are in the 2bbl Rochester. You have to unscrew the power valve to get the jets out, or a big magnifier. Mine are "52", but I don't know what size it should have. Do you want to sell the Rochester you had?

thats where on some carbs is a bowl vent. it had a reed valve and a hose that goes to the charcoal canister. the carbs more for emmisions had the holes drilled to use the valve.
