More than likely being in cali the yota carb is not vented to the atmosphere , the holley is and the gas is evaporating .

try this next time it sits for a long period of time .

Before starting it pull off the air cleaner , look down in the carb wit the choke open and pump the throttle by hand , if you see fuel squirt the bowls have fuel , if you don't see fuel then the bowls are empty and the car isn't going to start till you crank it and the fuel pump fills the carb up enough for it to start.
