Most likely it's toast.
A word of caution here. Checking a vacuum advance "by mouth", could
easily lead to ingestion of raw gasoline into the lungs. Too many times
I've seen V/A units with as much as a teaspoon of gasoline in them, for
various and sundry reasons. Accidently getting that much gas into your
body is gonna cause problems that ain't easy to fix!

No, the smaller (lighter) of the two controls the rate of inital advance
(which is relatively rapid), while the larger (heavier) controls the rate
of advance in the later stages, whis is slower.
The heavier spring should also be a loose fit on the mount pegs.
