Fuel Evaporation

I have to crank for a few seconds to start my '65 Cuda after it sits for a week or two

Totally normal.

If I drive my dart (67 273 2bbl) and let it sit a week, 2 pumps, crank, another pump, crank, usually fires up.

If I drive it, then the next day drive it, 2 pumps crank and it usually starts.

BTW, a new insulator usually comes with a rebuild kit.

Found just the 1/4" insulator...
