A word to swollen, gasoline or solvent-soaked gaskets and o-rings.
These shrink back into their proper size, after airing and drying thoroughly.
The same goes for diaphragms, for example, in cv-carburators. (That good quality parts shouldn´t swell and soak at all or that much... is a different matter...)

Carburator bowls don´t have to be airtight. In fact they have vents...though these days, they´re led into some emission control systems.

Of course, the bowl should be liquid-tight.

I go along with the thesis of a clogged idle (primary) jet. (..but the needle valve may be cleaned, adjusted and tested as well.)
