If anything, I'd think you'd want it the other way 'round (thicker stuff in
summer).

Snug should be enough I think. Perhaps a new gasket would help, a thin coat
of Hylomar on the gasket probably wouldn't hurt either. If the mating
surfaces are clean & undamaged the gasket should work -- but you might also
take a look at the fuel level in there to be sure it isn't too high. You
can lift the float out with a bit of 'L' shaped wire and give it a shake --
sometimes they get some fuel in them from a pinhole leak and that can cause
them to not function properly.
