I find that my Studey, which has an electric fuel pump and pressure regulator, starts so much quicker, especially after it has been sitting a while.
But when I go to start my '34, which has a mechanical pump, the starter turns and turns and turns.... and turns while the pump is trying to fill the carb bowls. Once that happens it fires.
The electric pump gets fuel to the bowls quick and the engine starts immediately.
The '34 will get converted soon.
I do see basic Edelbrock electric pumps in just about any parts store in case of a failure.
