Difficult cold start

Letting car sit for several days, fuel evaporates and now no fuel in the carb bowl. Best way to solve the problem is to an electric fuel pump, if the problem is no fuel after the shut down for any length of time. As was mentioned above check for a good squirt of gas down carb throat after the lay off. That'll tell if it's a fuel problem. Could also be a weak fuel pump. We can only suggest things, but you have to do the work to find the answer.
