Sounds pretty normal to me. The fuel evaporates from the bowls and the mechanical fuel pump is driven off of the cam, so the engine needs to crank in order to bring more fuel up to the carb. Once it gets fuel and fires, the engine is spinning the cam quickly enough to really get the pump flowing fuel. An inline fuel pressure gauge is an easy add on and could help diagnosing any other problems.
