Too cold to start car

There's no cover on QF - its basically a Holley 4150 design.
Either
>the float needs to be set or reset - Holley used to recommend that before installing due to possible bending of the tabs on the float arm during shipping.
or
>There's dirt - machine chips hanging the valve up.
These above will be obvious from looking at the sight glass and whether its overflowing from vent and boosters.
Or
>Leaking past Bowl and block gaskets. This will continue to leak with engine off.
or
> leaking at float adjustment lock screw gasket. Top of bowl - will stop with engine off.
or
> leaking at inlet fittings. Will stop with engine off as soon as pressure in line drops to zero.

Dry it off. See which it is.
Place rags where they can dry safely.
