I have a Holley 600 CFM carburator (i.e. P/N 0-80450).

What is behind the Idle Mixture plastic screws/caps?

Can I remove those plastic caps?

The reason I'm asking is that when moving them from one end to the other, it doesn't really make much difference. Would I be able to better ajust the Idle Mixture if I was to remove the plastic caps?

Thanks,
Daniel.

Daniel; Yes,you can pry them out.The idle mixture screws are under the caps. Steve

Thanks for your response 67chevy2, I removed them yesterday, it was real easy.

Thanks,
Daniel.
