1972 Thermoquad (340) Main Jet Well Inspection Question?

When I rebuilt the Thermoquad I was pleased to find the main jet wells had not become unattached so I did not service them in any way.

Now with carb installed and vacuum leak (idle increase with hand placed over air horn) I removed the carb for inspection. I find the main jet wells are still attached as before. However, I did find little puddles of gasoline in the little depressions they sit in (where the green handle is pointing). Is that normal or a problem? Thank you.
