Will,

Several possibilities come to mind ...

1. Float set a bit low so the needle and seat are not 
staying closed (maybe not a problem as long as fuel pump is 
working properly).

2. Damaged needle / seat - all it takes is a small nick or 
scratch

3. Choke setting wrong and/or bad electric choke (may not be 
getting voltage which is easy to check).

4. Mechanical fuel pump starting to go so it doesn't 
"maintain" pressure when the engine is turned off, allowing 
gas to drain back and actually "siphoning" gas out of the 
carb bowl.

If it works well in warm weather, check the choke first.

If it acts the same in all weather, check the fuel system.
